On the merits, the Turkish argument offered against the Patriot is grossly ignorant in that Israel's Iron Dome is not equivalent to the Patriot. Iron Dome is a terminal defense system against small rockets, principally launched from Gaza, Lebanon, and Syria. Against longer range missiles, Israel has several other systems and is looking to deploy a new model based on the Patriot.
As for the record of Patriot systems defending the Saudis, antimissile defense protocols are to the effect that not all incoming missiles are worth shooting down, only those projected to hit where they would do harm. This spares interceptors when attacking missiles are so badly aimed as to not present a threat. Knowing the true score, the Saudis and other Arab states continue to seek more Patriot systems.
Most of all, logically, if Patriot is so bad, then why is Putin so upset about it being sent to Ukraine? In truth, Patriot missiles and radars stationed in Ukraine would help not just Ukraine but would also help block Russian missiles and bombers from menacing NATO's eastern flank. Take that, Vlad, you idiot loser.
Isn’t this interesting?!?
Another Putin deception: look over here despite Ukraine losses, ignore Putin continuing to expand Arctic defenses
