Although I expect my government to have a greater obligation to its own people than those outside it, I also would prefer (sadly not expect) them to take a longer-term view than "what suits the situation at the moment."

If putting out worldwide propaganda is expected to have a long-term effect of degredation of public discourse, I would expect my government to take this into account and temper their actions. In fact, whether or not it is known today to have this effect, I'd hope my government would analyse these things and take them into account when making policy.
