You must be a confused on what it is America does around here. Forget the public distractions of television and the political discourses.
Ask yourself a question, why isn't Russia in Europe right now? Why are pirates not commandeering trade ships? Like it or not youre asking for your securities to be removed. Or wishing it.
The fact that Russia is struggling to sustain a war with a country with relatively weak military power, should indicate why your statements are delusional. That aside, the UK and France have nuclear power. Germany, Netherlands, Belgium and Italy have nuclear weapons sharing statues.
If we take away morality, and the fact that no one wants to have ww3, what makes you think they can do any real damage to Europe?
And the pirates comment is hilarious, when Europe has the UK and France.
You greatly overestimate what the USA does for Europe, and the impact then disappearing would have on the continent, across the entire ocean from them
Why? They rolled Iran's proxies, and (if western media is to be believed) Iran itself has been shown to be a paper tiger. Their big ballistic missile attack was neutered, and the big air strike on their soil was reported to be very devastating to air defenses and missile construction.
So we have a situation of Schrodinger's Iran. They are simultaneously super dangerous, and to quote Kamala Harris "Iran is greatest U.S. adversary." Or they are no match for Israel's superior technology and intelligence agencies.
Well, sure, but Israel is literally surrounded by enemies. It doesn't seem like it because of big daddy USA. But without them they could easily team up and attack from multiple sides. Especially if they get backing from Russia/China/UAE .
