As far as the F35 program which was started in 1992 and approved by the Bill Clinton administration, it was a huge success for the military industrial complex... Trump inherited the problem and Congress plans on continuing it.
“The national debt has eclipsed $27 trillion — or more than $200,000 per household. But instead of making a concerted effort to curb spending, lawmakers are determined to double-down on costly boondoggles. Case in point: the F-35 fighter jet, estimated to cost more than $1.5 trillion over the course of the program. Despite long-standing maintenance issues and supply chain concerns, lawmakers recently greenlit $9.6 billion in funding for 96 new F-35s — 17 more than the Trump administration requested.”
