Of course it is, but I don’t consider it more important than every other economic or social justice issue. If pursuing campaign finance reform means undercutting those fighting voter suppression, or corporate deregulation, or bathroom bills, or police reform because it’s a good way to score points in an intra-party pissing match, then I want nothing to do with it.
Perpetual war is basically the natural state of a Great Power, and getting into every fight you can to defend your “dignity” and prove that “you’ve still got it” is basically how powerful states keep their rivals from infringing on their sovereignty or co-opting the guarantees and assurances that their citizens live with. The reason states become powerful is to attain security, and the reason those states write their histories in blood is to maintain that security.
I’ve mentioned this before, and it’s a bitter pill to swallow, but American Empire has a popular mandate, because those perpetual “victorious” colonial wars and the hegemony it perpetuates convinces the American people (and people who live in its closest allies, like us) that we’re safe and that any attempt to attack us will be met with overwhelming, irresistible force. “Perpetual War” sounds bad (not just because it is), if you frame it like that, but if you frame it as upholding the assurances of safety and security that the citizens of the empire cling to, then it becomes considerably more popular.
If the US response after 9/11 shows anything, it’s that the American people as a collective are willing to countenance a lot of nasty measures to maintain their myth that they are safe, and that anyone who attacks them will be crushed.
