hardly earned tax money is being paid to Israel to purchase weapons systems that the US is unable to build itself. Who cares that they will be used to protect American military forces. Ol' Porky's gonna squeal like a burchered hog!

Iron Dome is both combat proven and as the article points out in 2017 it was taken to White Sands and evaluated by the US military who were happy with it and that is why they want to spend $373 million to buy 2 Iron Dome batteries.
This is not political its a military choice based on the fact that Iron Dome meets the needs of the army and is the right price.

The price for an Iron Dome battery used to be around $50 million. Interceptors originally cost about $100,000 each, coming down to around $50,000 each. Then Raytheon earned co-production rights (initially to the interceptor), and the Tamir now goes for $150,000, with other components also going up in price. Is this what happens when American defense contractors eye the richer US customer?
