The NATO relationship effectively turns Europe into vassal states - we don't have German or French bases on US soil, only the US gets that out of NATO. So it's a 'subsidy' only in the sense that the US is protecting its property.

People get angry about the Israel aid not because of the volume of funding, but because of the human rights/colonialism problems that the US subsidizes. I personally feel that way, but at the same time I understand the realpolitik deal with Israel - I believe the purpose of keeping Israel there is to prevent some version of the Ottoman Empire from re-forming.
