https://www.france24.com/en/america...-us-will-respond-decisively-if-russia-invades We all know what 'respond decisively' will be. Is not it?
It will certainly include moving a lot more forces into Poland and Romania, and giving Ukraine a lot more weapons to kill invading Russians with.
My plan is to get a giant projector and start a Monty Python marathon on the clouds and over a Led Zeppelin concert sound system. Both sides will probably overthrow their governments.
