Is anyone surprised? There is this inexplicable affinity between Trump and Putin. It's genuinely baffling, since it serves him very poorly (there is strong support for Ukraine in the US). What do you make of it is up to you, whether it's just his general admiration for dictators or something else. Ukraine is absolutely right to go its own way, with or without American support. Fortunately, the EU appears to stand firm, at least for now.
I don't know. Maybe he'd attack Russian proxies in the middle east, that have killed large numbers of their citizens during recent protests, like Iran.
He's probably not lucid enough to even know _why_ he granted a nice shiny federal pardon to the guy who funded Federal Grant No. R01AI110964 through the NIH to Ecohealth Alliance for research at the Wuhan Institute of Virology. But the rest of you seem to be equally OK with ignoring why that happened, so I dunno. Maybe I'll take you seriously about Iran as a result?
