General instability does not make a world war. It takes quite a lot of deliberate effort for that to happen. Undisclosed aid to Iran means nothing, and Pakistan India border skirmishes are unrelated to Iran.
The most likely scenario I could see is if the US gets bogged down in a drawn out war with Iran, and other powers, China specifically, exploits that situation to do their own expanding. It helps that the US has never been weaker, and that its leadership is easily exploitable of course. Although it is also unpredictable.
