If taxpayer dollars are being used to kill those children, I'm totally favorable people see in graphic detail what their taxes are buying them overseas. It's a matter of public transparency and accountability. Otherwise democracy doesn't work.
Yes, "you are responsible for the predictable consequences of your actions" is the most elementary moral principle. Here, "you" is those deciding and implementing US foreign policy, which overwhelmingly supports the slaughter in Gaza (via Israel), and the depredation that preceded it (via Egypt and Israel).
Israel would be far more violent toward Gaza if they had no western support. Ironically the US military aid is actually whats stopping them from flattening Gaza here.
I disagree, and the history of US presidential influence (Reagan, GH Bush) suggests otherwise.
