All of these things you are talking about are only for the war effort. These are only for a small part. There are some valuable things in war, but the real innovation and infrastructure are obtained from civilian use. I know what you mean. But you may not understand what it means to invest in a country's infrastructure for the time being.

I actually work on big, nationally-significant infrastructure projects and they're always short of funds because peacetime governments prefer spending the money on welfare and companies see maintanence as nothing but a cost center.
Bridges only get fixed, if someone needs to drive tanks over them, and then they get fixed in record time and at any price.
they do also fix the bridges if them being too weak to take the traffic for the supply lines, for almost anything, munitions and weapons are not all of it, they also need clothes, medical supplies
security is a high level issue but what security means for us plebs and for these warmongers are different things
if we see, what i think we will see maybe in our lifetimes, where the operational scope of a security system is at the level of a county or shire, a lot more of those small things that get lost in the big scale get handled
the escalation from state to federal to union level of focus of security leads to a steady decay of the small things, and the thing is that they don't actually realise something is wrong until one day the enemy rolls up and annexes it
security actually is more effective if its decentralised, even if the enemy is large, because the enemy has a scope scaling problem that the small units don't, and if they are chatty with their neighbours, it doesn't require forced central command to work
it is true, that security is the uppermost requirement in all cases, because if it's not attended to, it gets coopted and anexed and infiltrated
This is a tragedy. These tanks and artillery will only go to Vietnam, Iraq, and other war-torn countries. These funds will only build bridges and roads in those countries, not in the United States. These bridges and roads will eventually be destroyed by war. The money used to produce planes, artillery, and bullets will only go into the pockets of a few people in the military-industrial complex.
The tens of trillions of dollars spent on foreign wars in recent decades have been exchanged for planes, tanks, artillery, and bullets. If these expenses were exchanged for student education funds and infrastructure construction expenditures, the problem of insufficient funds you mentioned could be solved quickly.
I don't live in the United States. I'm referring to the crumbling German bridges and trains going off of rails, while a third of the federal budget goes to unemployed and retirees.
The same sadness. Tanks were unable to roll over every bridge and road in the German countryside.
When they aren't murdering people, they are robbing them and giving the money to agitators to maintain their dominance.
Sooner or later they will lop the branch they sit on. And anyway, there might be a really big reckoning coming for them. I believe it is going to happen soon. 150 years of democide is enough to warrant their permanent expulsion. One long foretold.
