I remember this conversation. Here's a debate I did on the invasion of Crimea from 8 years ago:
Now that Russia has actually invaded, what do you think the US should be doing? If you were president, what would you do? Would you respond to international pressure to punish Russia at all?
The question is oddly retrograde. The US response has been highly engaged in the past six weeks and the punishments laid on Russia already are pretty deep- the Russian stock market will partly re-open today after being closed for a month, GDP forecast for 2022 has swung from 2% growth to 7% shrinkage, the Russian internet has been reduced to ballet performances and fishing shows, the Russian people are showing escalating signs of rebellion. Biden has demonstrated a lot of leadership in uniting NATO against Russia while also denying Putin any legitimate new grievance in Europe. Biden led Congress to a bi-partisan condemnation of Russia (splitting off the radical anti-democracy faction) and a giant rapid response arms package.
To ask what we should be doing seems to ignore that we've already done pretty much everything on the list of things we can do short of going to war.
To ask whether we should respond to international pressure suggests that the US was not the nation leading the international pressure over the past six weeks, which we were to a significant extent.
I think Biden has done what he can and should do up to this point, diplomatically & economically. Now it is time to listen to the generals. If I was a general, I might point out that Putin's own life is the single point of failure in all of this genocide and destruction. The minute Putin is gone, this whole crisis ends. However much such a suggestion violates international law, if I was a general I would definitely be offering my President some stealth assassin drone options, some cyanide tea options, etc. I don't think any International court would really fault the assassination of a mad dictator carelessly threatening to nuke everybody.
