Bush Sr presided over the collapse of the Soviet Union, liberated Kuwait, defeated Sadaam, and unified Germany in NATO, to name just a few. His disaster was political.
And Bill Clinton presided over a balanced budget and welfare reform..and your point is?
The USSR would have collapsed regardless of who was occupying the White House at the time. Bush Sr. raised income taxes after pledging not to. Then, as an election year stunt, reduced withholding without actually bothering to cut taxes thereby screwing millions.
He unilaterally removed shipboard tactical nuclear weapons, and started the "peace dividend" military drawdown that continued under Clinton and which we're still feeling the effects of today.
Not to mention signing the ADA into law.
