I'm not optimistic that the West can sustain support for Ukraine, which in any case has always been a tale of too little, too late. Russia's economy may be relatively modest but Putin controls it; no Western leader controls a Western economy. Moreover, NATO stocks are now very low for a wide variety of key weapons and materiel, and we have no capacity to ramp up manufacturing.

As Ukraine strikes into Russia, chances are this will merely convince ordinary gullible ignorant Russians that Ukraine/NATO really is a threat and that Tzar Putin was right all along. Thus they will continue to bear whatever costs Putin's war imposes - costs which are actually negligible compared to the devastation Russian weapons have wrought on Ukraine. In the end, Putin may easily outlast Western resolve and end up with what he wanted: a puppet regime in Kyiv.
