Yeah, that's frankly the best thing we could do right now. Not really sure about shipping weapons, though of course I have no say in this. It's certainly possible that the Russian advance is as shambolic as Twitter makes it out to be and the Ukrainian army has a fighting chance of stabilizing the frontlines and the supply line over the western border is enough to force the Russians to offer terms that Kiev can accept, but cheering civilians on while they take potshots at Russian tanks until the fuel-air bombs start flying is not the next best solution. Neither is a twenty year insurgency that leaves the country in ruins and two generations decimated, no matter who wins in the end.
