There are huge financial consequences for even rich GCC countries if they cross the Americans. Needless to say, overpopulated, resource-starved poor countries like Pakistan have no chance against America/American allies sanctions. Pakistan's situation is made even worse because it has a much larger, much more robust economy/military neighbor ready to pounce given any weakness. The Indian member above mocking Pakistan to go and attack Israel is not only mocking but is also hoping that Pakistan would do such a thing.
At this point, until some alternate financial system comes up, America/allies economic tools are even more potent weapons than the aircraft carriers.
