Should the Americans have nuked Hanoi, out of anger that they "did badly" in Vietnam?
No. The US should have given Hanoi a warning on Day 1 and nuke it on Day 2 at the start of that stupid no-war war.
Russia haters here forget that Russia has no plans to be treated the way peaceful and cuddly NATO treated Serbia, Iraq, and Afganistan.
On the other hand, if Serbia, Iraq, and Afghanistan didn't invade Florida and Scotland...
No, we use the tactical nukes against Ukrainian lines,
Tactical or not, Russia's fate is not negotiable. Just as the fate of the US.
