Your non-sequitur America-first questions are really irrelevant to the discussion of whether or not we should be content with the US' death cult recruiting children for its illegal wars.

Where do I think the world would be without the US military today?

There'd be millions of innocent people - mothers, fathers, children - still alive, building their own nations into a better place to live. Mosul wouldn't be a burning pile of rubble, Raqqa too. There wouldn't be millions of innocent victims buried under the rubble that American citizens put them under. Maybe those of us in the West who enjoy these things could even have a vacation in the cradle of civilisation in Iraq and Syria, and actually enjoy the cultures of these peoples instead of reviling them.

If it didn't spend a trillion dollars a year on death and destruction of cultures it fears, America would easily have what it needed to offer its citizens world-class education and health care at similar standards to the rest of the western world. Clean water for its children. Perhaps, if Americans hadn't all signed up to their death cult, they'd have the funds for a better response to the pandemic, and maybe .. here is a cool thought .. average American citizens would have the skills to learn the languages and read the books of the cultures they fear so much today, instead of signing up to callously and evilly drop bombs on 'evil' (innocent) people whose language they can't even speak.
