it wouldnt surprise me to learn Israel has 20 or more Patriot systems operating all over that country.
And just read on Telegram ( not sure how accurate as i havent searched it yet ) but that Biden admin convinced Israeli Military Cabinet to join US in aiding Ukraine/defeating Russia
Which leads me to think, under it all, there is a genuine concern for this "Axis" of Russia, Iran, NK ( and possibly Syria and China ) that is/has been materializing and that the West is going to have to face at some point.
