Bruce and politics are kind of . . . . well, let's put it this way. Batman is opposed to crime, and corruption is a crime.
He doesn't want ANYONE to die unneeded, but the war's happened and doing nothing would be stupid. Donating armor to Iraqis would probably get his company boycotted because not just Bill O'Reilly but also Jack Ryder (although he probably tried to get something to the Iraqi peacekeepers), so his foundation just donates to the troops, huge PR boost, more profits, more embezzlement to equip his secret war on crime . . . .
