Entitlement costs already dwarf defense spending, and it's going to get a lot more dramatic over the next 20 years.
Entitlement costs aka the people getting money.
> Instead people take out loans and go into debt to keep up
Well that certainly depends on who you're talking about. US households at the median and above are in decent debt shape, including debt interest expenses in relation to household disposable income. The payday loan context trap for the working poor is still every bit as bad as it has ever been.
The biggest household financial threat right now are real consumer prices - including rent/housing, education, energy - rising considerably faster than wages.

the military budget is 50% of the US budget for FY22

(Two party system is broken and neither does a good job of serving the interests of their voters. "Vote harder" isn't practically effective and displaces blame to the victims. Ineffective, selfish and corrupt leaders have captured the majority of political positions, and until we get rid of them change is impossible.)
I agree that the military budget is problematic, but it's short sighted to spend too much time worrying about foreign aid. It's a very cheap way to wield influence.

The US and nearly everybody else. The biggest exceptions most recently? Sweden, Luxembourg, Norway. Gee, I just can't figure out why the US doesn't match Norway (or other tiny hyper affluent European nations) on such a matter. The only real exceptional outcomes in that list are Britain and Germany, and France to a lesser degree - outside of that the entire world is largely failing badly at that supposed test.
Meanwhile during that time the US supplied nearly half the world's food aid, while only representing 4%-5% of its population. A tradition of food aid going back more than a century now.
For example:
"The U.S. contributed $3.4 billion to WFP [UN World Food Program] in 2019, which was 42% of all contributions last year." - from the UN WFP homepage. And that's just to one entity.
Globally at present the US is supplying around 40% of the world's food aid all by itself (the number used to be slightly higher in the past and I think the US should do more, however that's still astounding coming from one nation).
You know what the US should do? It should pull its military entirely out of Europe and Asia, and let Russia and China run wild (they'd promptly conquer and pillage like it was the 1930s all over again). North Korea would be in South Korea before the final US troops were out of Asia; South Korea would cease to exist as we know it today within a decade. Then we should cut that related defense spending, and redirect that former defense expenditure to meeting that 0.7% GNI target (and helping the people ravaged by the inevitable large wars, which is how we used to approach the problem circa the WW1 & WW2 eras).
