The attempt to rescue the hostages was poorly planned. Watching a description of it on the History Channel, as they were describing the plans, it seemed as if at every opportunity they tried to make it more complex. Simple plans are far less dependant on functional equipment. The plans involved three separate invasions of Iran, with numerous elements expected to rendezvous within enemy territory. This is the sort of plan that looks great on paper, but leaves innumerable opportunities to get royally fucked up on the ground.
According to Air Force magazine: “The plan was staggering in its scope and complexity, bringing together scores of aircraft and thousands of men from all four services and from units scattered from Arizona to Okinawa, Japan.”
There was very little information available as to the layout of the embassy, and where the hostages were being held. In order to account for this uncertainty, the task force had to be large, requiring at least six helicopters. Eight were provided, allowing for at most two to be unusable at any point. The pilots had to fly these helicopters over flat terrain at night without accurate weather information.
By the time they rendezvoused with the C-130’s at Desert One, two had turned back, and one was unoperational. Their arrival time was also inaccurately calculated, causing the C-130’s to spend an extra 55 minutes waiting for them, wasting fuel. When it was decided to abort the mission, one of the reasons for the ensuing crash was the haste in which it was necessary to get the C-130’s into the air. Another factor was the lack of any specific plan for the scenario af aborting.
Had there been six helicopters still available to leave Desert One, they still would have to have flown to a hideout outside Tehran, successfully rendezvoused with agents with vehicles, drive to Tehran, and actually rescue the hostages, without knowing exactly which building they were in. Then the helicopters would have to have then picked up the hostages and their rescuers, flown to Manzireh Air Base, rendezvoused with C-141’s coming from Turkey, and use those to escape the country.
To blame the failure of the mission on equipment failure is like trying to blame the fact that you couldn’t make a cross-country trek in your mid-sixties VW Bug on it breaking down along the way. In both cases, an unrealistic expectation of the reliability of the equipment was made.
Other problems with the mission were mentioned in the official report of the Holloway Commission which investigated it: “the rescue mission was a high-risk operation. … People and equipment were called upon to perform at the upper limits of human capacity and equipment capability. There was little margin to compensate for mistakes or plain bad luck.”
Much of the information I used is here. Certainly it was not solely Carter who was to blame for the debacle, but he should not be held entirely unaccountable for it.
Back to the OP, what I meant as to the relevance of Reagan’s intelligence is that the only way I can see to measure how great a President was is through the results of their actions. If, say, Dan Quayle were to become President and somehow cause world peace, he would be a great President, regardless of his inability to spell at an elementary school level. The success Reagan had with dealing with the USSR was due in large part to allowing many decisions to be made by people who were far better at it than he.
Giving the rich tax breaks is far different than giving them money, unless you believe that the primary purpose of taxation is to redistribute the wealth. Even after the Reagan tax cuts, the rich were still paying a higher tax rate than the poor and middle class. Since the bulk of the tax revenue comes from the rich (from what I recall), an evenly distributed tax cut would still be “giving” the rich more money.
The main failure of this plan was that the tax breaks and increase in military spending were not offset by cuts in social programs. In fact, the spending on social programs increased over the Reagan years. (By failure, I mean where the plan failed to be implemented, not failure of the plan itself, which would be another debate.) Thus, the necessary money was borrowed, resulting in all sorts of nasty side effects.
