WI Soviets instead of not voting for resolution about deployment of troops during Korean war they vote against it, effectively vetoing it.
Would this force Truman to DoW North Korea?
how does this affect contingents? IMO not much, US would send same, other Us allies likely as well and others if absent would only keep their symbolic contribution from appearing.
But how would this affect int'l relations? would Un be seen as useless, being unable to provide help for one country clearly under attack by another?
