“Ukraine can do what it wants, but there is no way for them to win this thing unless some other countries are willing to supply troops.”
That’s an opinion, not a fact.
“If the Ukrainians ramp up attacks against targets inside of Russia using US supplied long range missiles, you will see the Russian people unify behind Putin.”
Another opinion, not a fact.
Opinions based on whats been reported.

And it is my opinion that attacks on the motherland tend to unify and rally the people against the attacker, and there are many examples in history, 9/11, Pearl Harbor are two such American examples where an attack on the US unified a divided population in response.
