Pooya gave you a good answer.
Just think about this. If EU and Britain go into war, do you think that Russia will be alone? There are 27 countries in EU, most of them have a big economy and are technologically very advanced. If they go into war, there will definitely be an usage of nuclear weapons, right? And do you also really think that Russia will be alone? Besides Russia, there is China, Iran, North Korea and many other countries. Then behind them there are some other countries and so on. It will lead to World War 3. Who the hell do you think is going to manufacture an iPhone or something if there is a war and they die? Who the hell wants USD if people die and countries collapse? Think about it and don't write some illogical nonsense.
It would be great if you'd understand better what you're talking about.
Plus: if EU goes to war, there's little chance US can avoid it
If EU goes to war, the USA is automatically into it. Not a little chance, there is 0 chance that US can avoid it.
