People keep talking of nuclear winter or complete destruction being the big unacceptable cost, but really even loss of 100k americans is an unacceptable loss. This doesn't mean we shouldn't help Ukranians, but an example of a devastating retaliation against US would simply be smuggling one tactical nuke and blowing it up in a major city. I also don't think that killing millions of russians is itself an acceptable loss of life. For all the horrors of ukranian war the total loss of life is less than many single cities.
