The 1 trillion budget says the US can flex its muscles, but once sovereignty is at stake, the US army becomes an ineffective money sinkhole only good at committing war crimes, as the last century has clearly shown.

If the other side have sufficient nuclear warheads it does not really matter the size of the war budget.

You have to be willing to use them though and suffer the consequences. Having them isn’t enough on its own.

Exactly, and that isn't in the billionaires interest so it's not going to happen. They'd rather all their consumers attention be available to them than dealing with nuclear fallout.
