I literally couldn't care less about what US "needs". Russia "needs" Ukraine and similarly no one should be respecting them for it. You Americans think you own the world - you don't.
>>This is pure national security and economic security pragmatism.
Yes and I'm sure Putin sells his war in the same way to his citizens.
>>and I don’t want my country to collapse economically or militarily so taking Greenland is easy to reconcile.
If you think taking Greenland will do anything of that sort then you are deeply delusional. Trump and the other fascists will stuff their pockets and the inevitable conflict that follows will make your defence companies rich.
>>We kept the Soviets at bay
I'm sorry, what are you talking about exactly? The Soviets that fought with you to defeat the Nazis? The Soviets you have subsidized with billions of dollars during WW2 with weapons and supplies to defeat Hitler? Those Soviets?
>>The US propped up Europe for 70 years after WW2 and paid for its defense
I assume you never actually sat down to think why that is, and if it might have something to do with the fact that US both wanted to do this and it was in their interest to continue doing so. To now say something as stupid as "the bill is due" is uneducated at best, malicious at worst.
