Who's talking about warheads? He regularly lobs insults at allies at the drop of a hat but has yet to say a single negative thing about Putin. You never ask yourself why that is?
I think that actions are much more impressive than words on Twitter. Maybe that's just me because snowflakes seem to be so triggered and traumatized by words and free speech.
I'm fairly certain that Official US Sanctions circa 2017, moving significant military assets opposite Russia in Syria, ordering multiple missile and airstrikes against the Russian ally Syria, slaying 200-300 Russian mercenaries, and playing war games with Russia's former allies in their own back yard is a hell of a lot more negative and effective than anything Trump could come up with on his Twitter feed.
