Exactly. Russia/Putin can stop this war if they want to.
In the meantime arm the Ukrainians and cause the Russians to use up weapons and men who can’t be replaced, thereby making Russia less of a threat to NATO and the USA.
Giving Putin a bloody nose in Ukraine is fine with me, but let’s be honest: Biden and the media want to keep milking this war right up to the election, so Biden can distract everyone from domestic disasters and posture as a latter day Churchill.
How much of a threat is Russia to the US beyond its nuclear arsenal? Russia lacks the conventional military force to invade Europe. It is no match for NATO.
