No, it is sensical because it’s a clear red line that Putin and everyone under him knows is our red line.
If he crossed that, then all bets are off.
By doing what we’re doing, we’re not risking nuclear war in the case he’s bluffing, which he almost certainly is. In the case he isn’t bluffing, we’re still not a direct “existential threat” he can point to for anyone under him to escalate this more.
Look, I get it. Nobody at this point doesn’t want to get involved. But the people with a far better knowledge of this than HROT have decided that at this point, it isn’t worth risking escalation. Take from that what you will.
