Forcefully opposing the warmongering and imperialism of your rulers is the very first step toward political morality. It's not the only step, but it is the first step, because if you haven't taken that step then no other ostensibly moral politics you might espouse are meaningful. 

Your anti-capitalism is meaningless if you're not aggressively opposing your government's mass military murders for power and profit. Your anti-racism is meaningless if you're not aggressively opposing your government's butchery and exploitation of brown-skinned people overseas. If you're not forcefully opposing your government's warmongering and imperialism, then the rest of your politics are irrelevant, because they are false. A sincerely antiwar right-winger with all the wrong positions on all other issues is still a much better person than you are.
