It is never altruism. No self entitled altruist can ever be trusted.
Were you is SE Asia during the 60's? It was a French mess, and far worse than Algeria. And it all fed into well cultivated American anticommunist paranoia.

Whatever motivates or has motivated American behavior, still does not make Europe an ally any less responsible for its own self created horrors, depredations against humanity or a loyal friend of the US.
You (generically) are no one to criticize the US.
When Merkel and cohorts tried to stare down Trump at the G7 because of his then threats to impose tariffs, the media story concentrated on Trump throwing Starbursts candy out of his pocket on to the table in front of Merkel. The media almost completely omitted his following words to Merkel, "I'm all for fair trade. Let's eliminate all tariffs." All US goods imported into Europe suffer tariffs. Almost none for European goods imported into the US. Trump sinned and is sinning. He's leveling the playing field. Point your finger back at the US accomplishes nothing. Merkel was left speechless. How rare is that?
The US is a racist bigoted country which wants to shut it borders down against brown skinned illegal immigrants. How vile says Europe. Meanwhile the rising right of Europe is making the same demand for Europe. The people want no more Asian and African refuggees and politicians like Merkel are facing reelection defeat in their own nations. Macron calls Trump almost everyday for advice while excoriating him in public. Hungary is a permeant representative to the EU, but it has not accepted one refugee within its borders.
I could easily go on, but don't continue to give me crap about European moral superiority and lack of corruption. You have more of your own politicians who have served hard time for corruption than the US, and on both continents the big boys are are free to continue as they please. Brexit is your future. The US will remain one nation.
You better damn well pray we don't decide to close down our military bases in Europe. Local economies in Europe will be devastated.
Go munch on a Jaffa orange. The agrarian fields of Spain have suffered desertization. Venice is still an open cesspool and a decaying slum. Russia still fears German militarization. Norway's millennials are still the most wealthy in the world.
