Remember that Iraq war that Republicans lied to get people into it...
GOP and Trump love forcing people to do things as well... Iraq could have cancelled all college loans, housed the homeless and fix the Vets hospitals... And there would be still plenty of change...
GOP just steal big... Trump basically gave China TPP and then took the bribes...
Again, the US Constitution charges our federal authorities with the protection of their people from enemies domestic and foreign. You can argue that Iraq was no real threat to the US, but at the time, neither was Osama.
There is nothing in the Constitution that justifies feeding the people, and no, it's not covered under General Welfare. If if was, then the federal government would also be providing houses and cars for all of it's citizens.
