Go ahead and get involved in Yemen, let's see what happens. Your saudi friends with their much more powerful air-force cannot do anything to stop Houthi advancement, what can Pakistan with its much weaker airforce accomplish? Your involvement would make no difference to reality on the ground. The saudis wanted to use Pakistanis as cannon fodders. They wanted to send you into Yemen via ground, if that happened, your soldiers would have been send back home in body bags. Sorry, but Houthis would have owned you This is why Pakistan did not go into Yemen.
As I said, Iran does not give the slightest bit of care what you think. Your problem with India is your problem.This is a harsh reality for you, but India is a much more powerful economy and can offer Iran alot more. Pakistan should become a more powerful economy and then Iran-Pakistan can have great cooperation. However, even then, Iran would not stop its economical cooperation with India over Pakistan.
Your nuclear arsenal is not helping your economy nor is it helping your security situation, don't forget you're busy fighting terrorists within your own borders. The west snipped Iran's balls? The reality is, Iran is a much more successful player in region, by far, compared to Pakistan. Your nuclear arsenal are not worth as much as you think as your economy and security is a mess. In any case, not long in the future, Iran will have industrial scale nuclear enrichment capability (enough capability for an arsenal of nukes) and will be an economical power. Meanwhile you'll be bragging about your American and Chinese fighter jets whilst your economy is in shambles. Your nuclear bombs are more worthless than you care to admit.
