I wouldn't underestimate the GCC and Arab countries, they have made a lot of strides in the defence field and spent a lot of money on ToT. You must always prepare for the worst and expect your enemy to have the advantage.
Of course, they will have the blessings of USA and israel in their war against Iran, but in the end who will suffer? Muslims; Iranians and Arabs, meanwhile all israel will have to do is walk into Arab countries and take what it wants at will with no opposition.
Well there is a policy known as divide and rule and we guys seem to be suckers for it
