US box office makes or breaks virtually all movies made by US studios. Studios get a smaller cut of international proceeds. So even if a movie makes a lot of money overseas, if it bombs in the US it may well not get a sequel as the US is the primary film market.
But Bond isn't one of them - the historical context is that Bond films makes more overseas than in the US. So for an untried property, what you say is true. For Bond - not so much, as the expectation is that the overseas take will be larger than the US.
