I am a US citizen and I try to see the world as it is.

>Will the US help? That was a given even just 1 year ago, but now is strongly in doubt. With the current commander in chief, the US will do nothing except talk a lot of nonsense contradicting itself daily.

>What will happen to world trade?. World trade as we know it is done. National security interests will force strategic industries to be on-shored. New trade deals will only be made with a short list of trustworthy allies.

If Russia does attack, the US will take 1+ years to ramp up and we will take a long time before we reach Europe in large numbers. The rapid reaction forces we have are not prepared for the new way of fighting we see in Ukraine.
