Not just "good at its job" but specifically the greatest in the world. She's telling you she is going to increase funding for the military even more, even though we already out spend everyone else. It's a very right-wing position.

And specifically most lethal.

That's a weird choice of words. Yeah, militaries kill people, but the fetishizing of butchery is troubling. She gonna adopt Israeli policy of bombing hospitals?

Why do we need the "most lethal" military? Are we in danger of being invaded by Canada or Mexico?

Killing is different than winning. For example, the nazis killed 26 million Soviets, mostly civilians. That is roughly 17 percent of their population. The US killed something like 20 percent of the population of Korea. Both lost.

She could say "most effective" but she said "most lethal"

Imperialism and never-ending wars for sure
