Honestly - what you are saying makes no military or strategic sense at all. Iran should focus on destroying the military infrastructure in the GCC the US forces are using, so that the US forces cannot return to use them and once that is done, then it can focus on Israel.... Why should it focus on Israel now, and leave the option of viable military infrastructure in the GCC? Iran's strategy has been to push the US further and further away in terms of basing ability, and that this working as the US has the bulk of its refuellers in Israel..
