The Gulf states? I hate to break it to you Sunni but those Militaries are 4th rate at best, sure the Saudis and Kuwaitis have US equipment and some training but overall they are a very poor Military force, the Israelis would scorch them even without any help from us. The Iranians have the best Military outside of the US and Israel in the region, along with the Turks if you want to count them.
Pakistan has a top notch military that has rescued us on numerous occasions when we got into some trouble in that region. Not that I think they are going to attack Israel, but do not underestimate them.
Boy please, Pakistans Military is hardly "top notch" the Israelis would scorch them.
For one thing I am not a boy and Israel has a good military, but Pakistan has the seven largest military in the world and are the #1 contributor to UN peacekeeping missions. Pakistan has a larger more well equipped ground troops and Their air forces are about equal, though Israel has better technology and Pakistan has more planes. Israel has much larger navy and they are equally experienced and trained. It would be a fair fight no matter how much more you like Israel or hate Arab countries. I also like Israel better since my family is Jewish and I spent a lot of time there, but not enough to blind myself.
