Though, I would not be surprised if they actually have some of them, delivered by the United States and only under the command of use of USA.
Even if USA is their most important ally on this planet, it would be quite irresponsible of them to give those weapons to direct Israeli command, instead some USA commander in the middle east.
I have got the impression that when comes to military capabilities, Israel mostly rely on the quality of their training and not the number of combatants, they are a small country so they cannot possibly have many people to fight, they have to focus on train the few the have as much as possible and invest in technology to defend themselves.
People tend to over-estimatr the power of Israel as well, I believe their real power comes for the close alliance it's has with the United States and other western governments, without them Israel may not stand a chance against it's Arab neighbors.
The fight and their desire to fight comes from their wish to hold land and to defend the legacy for their future generations. One can call it Zionism or their right to exist, but one cannot deny their determination.
