Say them now or in the very near future. Or write down your thoughts in a card or letter. You may think we have a little time and will receive a little warning, and I do too- but the logical part of my brain reminds me of ***Game Theory***. Trump's move forces the leaders of Russia and China to hover their fingers above their respective red buttons now. Their is no other sane way to play this game. Trump is presaging World War, and the West has repeatedly express its willingness to pre-emptively strike Russia and China. The full nuclear resources of all the major powers could literally be flying at any moment from now on. In a ***real*** gunfight the man who fires first always wins if both are skilled- you can never win by 'responding'.
