Butter, in a heartbeat.
Mr. Heston is not amused.
Mr. Heston might well agree with me. We're not talking self-defense (at least I assume we're not, the OP references Canada as the "butter example", not Kuwait). If we're positing Canada, or Japan, or Switzerland, or Iceland, or Australia, then I see no need for military power projection. If we're positing Kuwait, or an IDF-less version of Israel, or Nepal, or Taiwan, where there are powerful nearby enemies, then obviously the butter must be sacrificed for retaining sovereignty, not just staying off the late-show cue cards.
