Why else has the US been overspending on military for decades and planting military bases and nuclear submarines all over the world, to become the world hegemony, if not to bully everyone in doing its bidding when push comes to shove?
I'm not defending the actions of the US, I'm just asking what are the other countries gonna do about it? Ally with Cuba, China, Iran and Russia to fight the US? Unlikely.
UK, Canada, Australia, New Zeeland are 5 eyes members and therefore lapdogs of the US, and the EU as much as they dislike the US due to Trump, has a laundry list of urgent domestic issues like Russia, no cheap energy, no high growth industry like tech, ageing population, economic stagnation or even decline, collapsing welfare and pension system, illegal immigration leading to a rise right wing extremism leading to crackdowns on freedom of speech and censorship leading to further social and political turmoil. So how is the EU gonna retaliate when they can't even keep themselves together?
What can they do now, when the US holds all the cards? Their only hope can be that the US collapses from internal issues, just like the Roman empire, but until then, they literally have no screws to turn on the US and just like the EU, Switzerland, etc, are forced to accept the terms of the US or have their already fragile economies suffer even more.
