“ It does feel like the financial Rubicon has been crossed.”
It was crossed when US invaded Iraq and started the cycle of $7 trillion for endless Middle East wars and nationbuilding. “Fiscal conservatives” never objected. They revealed that “fiscal conservatism” is a fraud that only opposes spending money to help Americans in American; blowing trillions on foreign adventures is fine with them
You have a point about money blown in the Mid-East, and I fully expect that we’ll be dumping money in Syria by summer, because Assad is bad or something.
