There was no one man who stopped the program from being exported or developed at a proper rate, it was a lack of support through out the life of the program. At this time congress worked a lot more together -bi-partisan. This was a major screw-up by bunches.
The program started during President Reagan's administration. It was never a high priority though, program since it started back in 1981. It started as a program to replace the F-15 but, the F-15 had such a technical superiority it remained a program with low priority. In 1982 the Israeli AF verified the advantage of the F-15 over the MiGs in the air battles over the Bekaa Valley, where it shot down dozens of MiGs... without the loss of a single F-15s! Many in the USAF felt an up-graded avionics for the F-15s and F-16s would be all that would be needed for the future.
Then US intelligence found out the Soviet AF was having real delay problems in the development of the MiG-29s and the Su-27s. The Su-27 program was stopped and restarted in 1981, they lost four test planes and test two pilots! All this time the ATF program remained on the back burner. The program suffered another loss of support from the USN in Dec. 1990 President HW Bush's -Secretary of Defense Dick Cheney cancelled the USN's A-12 stealth bomber program! In 1993 President Clinton ordered that the YF-22 / YF-23 that the program should to be restructured. The manufacturers and sub-contractors were told the total production be cut at least in half (in steps) and delayed by at least by seven years! The original schedule for the F-22 was it was to become operational in 1994-1995!
All these low priority and slowed development meant the price would at least triple and the production dropped (in steps) from 750 down to 187 fighters.
President G.W. Bush did not increase the priority of the program and by this time Congress was complaining about the cost. Secretary of Defense Donald Rumsfeld was cutting most anything that he could. President Obama's Secretary of Defense continued Robert Gates continued what Rumsfeld and, other secretaries of state had been doing. All these people and their misjudgments have cost this country dearly in time and money. It was never a program that had much going for it other than the USAF.
