Opposing opinion:
Where have all the Gaza rockets gone?
If only 10 percent of the rockets fired from Gaza were intercepted by the Iron Dome system, where did the nearly 430 rockets that apparently fell nowhere vanish?

Patriot missiles in Operation Desert Storm
Main article: Patriot missile success rate
The Patriot Missile was used in Operation Desert Storm to intercept descent-phase SCUD missiles fired by Iraq. The U.S. Army claimed a success rate of 80% in Saudi Arabia and 50% in Israel, claims that were later reduced to 70% and 40%. But President George H. W. Bush claimed a success rate of more than 97 percent during a speech at Raytheon's Patriot manufacturing plant in Andover, Massachusetts during the Gulf War, declaring, the "Patriot is 41 for 42: 42 Scuds engaged, 41 intercepted!"[1]
In April 1992, Postol told a House committee that "the Patriot's intercept rate during the Gulf War was very low. The evidence from these preliminary studies indicates that Patriot's intercept rate could be much lower than 10 percent, possibly even zero."[2]
The House Government Operations Subcommittee on Legislation and National Security later reported,
The Patriot missile system was not the spectacular success in the Persian Gulf War that the American public was led to believe. There is little evidence to prove that the Patriot hit more than a few Scud missiles launched by Iraq during the Gulf War, and there are some doubts about even these engagements. The public and the Congress were misled by definitive statements of success issued by administration and Raytheon representatives during and after the war.[3]
Postol later went on to criticize the Army's "independent" Analysis of Video Tapes to Assess Patriot Effectiveness as being "seriously compromised" by the "selective" and "arbitrary" use of data.[4] The Army ultimately downgraded its assessment of the systems' effectiveness.

Some of the largest hoaxes of this type took place under Presidents Regan and Bush II. I would have to take the time to find the references
