Good point. I would say that even if we know how funding works we cannot predict the future. We do not know what circumstances will prevail at the time actions/decisions need to be made. With the best of intentions it is still possible to have to renege on a promise made. My argument is don't make promises. But even where they are made we should just read them as a general statement of intent. As an example a certain government promised to conduct 100,000 covid-19 tests per day by a certain deadline. When the deadline hit they only got as far as 80,000+ or so. They got hammered for failing to meet the target. But I'm thinking yes they missed the target but we're a lot better off than when the promise was made. If they hadn't made any promise and achieved the same result the press might have celebrated it (probably not).
