Some believe that there has long been a plot to destroy the USA:

The Planned Destruction Of America: “If They Can’t Collapse It Internally They’ll Attack The U.S. Externally”
July 20, 2017
From within and from without. Before our very eyes, we are seeing actions taking place both within the U.S. domestically and outside of it.  The scripted plans were set into motion decades ago, and are seeing fruition now, with increases in activities leading toward the planned downfall of the U.S.  The architects follow a very “Orwellian” pattern: it isn’t important who takes the reins of power, if that power is used to promulgate the continually leftward-moving paradigm shift and the continuance of power. These oligarchs are globalists who wish to remove the national boundaries except to use the governments in an administrative fashion to control the masses.
Sound radical? It is, as in “Rules for Radicals,” by Saul Alinsky, in a concept known as “organizing the organized.”  In such a fashion, the oligarchy will control the population through the captains…the “duly-elected” commander of the ship of fools. …
Technology will help propel the New World Order into existence.
They’re working really, really hard on controlling all the cash and removing physical cash from the hands of the people. …
Europe is tottering akin to a group of drunken men in various stages of sodden decay. European nations are caught between the need to maintain their national identity and the desire to join hands and sing “Kumbaya” in 50 different languages as they embrace the utopia. …
If they can’t collapse it internally, they’ll attack the U.S. externally.
Civil unrest, economic collapse, and an attack on the current administration are the vehicles used to promote the fall of the U.S. domestically. Warfare (initiated by a foreign nation or by the U.S.) is used outside of the country. Both use different approaches to work toward the goal of the United States coming to an end.  Read history, especially Solzhenitsyn to see how this occurs.  Before a nation comes to an end, its citizens are in denial that it truly has reached that point. The United States is in its final days, now. It will come to an end. http://www.zerohedge.com/news/2017-07-19/planned-destruction-america-if-they-cant-collapse-it-internally-theyll-attack-us-ext

The Bible shows that the USA will come to its end and that time is getting closer. The USA will be destroyed under a dictator from Europe called the King of the North. This is shown in Daniel 11:39 and there is more information about him in the Bible in Daniel and Revelation. He will be ‘elected’ in some manner (cf. Revelation 17:12-13). He will also control financial transactions per Revelation 13:16-18.

As far as Europe goes, it is not really following Saul Alinsky’s Rules for Radicals. Europe believes that it is being forced to rearm. Notice the following from the German press:

What would Europe’s ‘fate’ be without the US?
German Chancellor Angela Merkel says it’s time for Europe to take its fate into its own hands, given a Trump administration attitude toward European defense that’s too tepid for the comfort of some NATO governments. Countries that are underspending may naturally be feeling overexposed, with the US threatening to “moderate” support for those not meeting the alliance mandate of two percent of GDP budgeted for defense. If US President Donald Trump made good on his threats, what kind of security could Europe provide itself?
Former European Defense Agency official Nick Witney believes there’s never been a more pressing need – nor a better opportunity – for Europe to get serious about this. With Trump’s threats coming from one direction and Russia’s from the other, the election of France’s new cool-headed president, Emmanuel Macron, gives Merkel the best set of circumstances she’s going to get for shoring up Europe’s self-reliance.
Witney, who’s now with the European Council on Foreign Relations, said Europe should quit whining and see this as a helpful wake-up call. …
Sven Biscop, director of the Egmont Institute, Belgium’s Royal Institute of Foreign Relations, agreed Europe’s best hope for self-sufficiency is to finally cooperate on defense investments and expenditures. With what Biscop calls the “Trump First” policy, he told DW that US interests may or may not coincide with Europe’s and when they don’t, Europe won’t have a choice about whose hands hold its fate. Therefore, Biscop recommends a “Europe First” attitude be adopted to match. …
NATO-watcher, the German Marshall Fund’s Bruno Lete, agreed Europe is hamstringing itself despite possessing one of the world’s most powerful and technologically advanced armed forces. “Without the unique coalition-building capacity of the United States inside NATO, today Europe would struggle to unite and effectively organize its own defense,” Lete said, citing the need for US strategic enablers “and the command-and-control and intelligence and surveillance platforms.”
“It is particularly in these domains that Europe is lacking punch, and where the US is adding so much value,” Lete said. “If Europe is to take care of its own defense, it is this gap that it will have to address first.” 053017 http://www.dw.com/en/what-would-europes-fate-be-without-the-us/a-39051988

So, Europe thinks that it has a technologically-advanced military and mainly needs to reorganize to fill in some gaps to no longer need the USA.

Consider the following Bible prophecy involving a European power (called Assyria before):

5 O Assyrian, the rod of mine anger, and the staff in their hand is mine indignation.
6 I will send him against an hypocritical nation, and against the people of my wrath will I give him a charge, to take the spoil, and to take the prey, and to tread them down like the mire of the streets.
7 Howbeit he meaneth not so, neither doth his heart think so; but it is in his heart to destroy and cut off nations not a few.
8 For he saith, Are not my princes altogether kings?
9 Is not Calno as Carchemish? is not Hamath as Arpad? is not Samaria as Damascus?
10 As my hand hath found the kingdoms of the idols, and whose graven images did excel them of Jerusalem and of Samaria;
11 Shall I not, as I have done unto Samaria and her idols, so do to Jerusalem and her idols? (Isaiah 10:5-11, KJV)

The USA is “an hypocritical nation.” It also fills the role of the prophesied Samaria, which will be destroyed. Europe does not think that it wants to destroy, but it will. European leaders want a re-emergence in European dominance in the world. The USA is pushing Europe to increase military spending. The time will come when Europe will consider that the USA is in its way (cf. Daniel 11:29-30) and finally take it over (Daniel 11:39; see also USA in Prophecy: The Strongest Fortresses).

Now, the Bible shows that Europe will think it did it on its own, but will itself also suffer later:

12 Wherefore it shall come to pass, that when the Lord hath performed his whole work upon mount Zion and on Jerusalem, I will punish the fruit of the stout heart of the king of Assyria, and the glory of his high looks.
13 For he saith, By the strength of my hand I have done it, and by my wisdom; for I am prudent: and I have removed the bounds of the people, and have robbed their treasures, and I have put down the inhabitants like a valiant man:
14 And my hand hath found as a nest the riches of the people: and as one gathereth eggs that are left, have I gathered all the earth; and there was none that moved the wing, or opened the mouth, or peeped.
15 Shall the axe boast itself against him that heweth therewith? or shall the saw magnify itself against him that shaketh it? as if the rod should shake itself against them that lift it up, or as if the staff should lift up itself, as if it were no wood.
16 Therefore shall the Lord, the Lord of hosts, send among his fat ones leanness; and under his glory he shall kindle a burning like the burning of a fire.
17 And the light of Israel shall be for a fire, and his Holy One for a flame: and it shall burn and devour his thorns and his briers in one day;
18 And shall consume the glory of his forest, and of his fruitful field, both soul and body: and they shall be as when a standardbearer fainteth.
19 And the rest of the trees of his forest shall be few, that a child may write them. (Isaiah 10:12-19, KJV)

Earlier, I mentioned the King of the North. In Isaiah 10:12, he is referred to as the king of Assyria. This is the same person. The Book of Daniel shows that sometime after the USA is destroyed (Daniel 11:39), the King of the North will be as well (Daniel 11:44-45). And the Book of Isaiah shows the same thing happening to the king of Assyria (this is also referred to in Joel 2:6,20).

The end of the USA is coming. It is not here yet, but events in the USA and Europe are pushing us closer to that time. And Europe will not escape, despite its coming initial successes.
