Clinton, who even with all his faults was still a far better president than Bush, offered a few critiques:
Clinton said the Bush administration had decided to invade Iraq "virtually alone and before UN inspections were completed, with no real urgency, no evidence that there were weapons of mass destruction."
The Iraq war diverted US attention from the war on terrorism "and undermined the support that we might have had," Clinton said in an interview with an ABC's "This Week" programme.
On the US budget, Clinton warned that the federal deficit may be coming untenable, driven by foreign wars, the post-hurricane recovery programme and tax cuts that benefitted just the richest one percent of the US population, himself included.
"What Americans need to understand is that ... every single day of the year, our government goes into the market and borrows money from other countries to finance Iraq, Afghanistan, Katrina, and our tax cuts," he said.
"We have never done this before. Never in the history of our republic have we ever financed a conflict, military conflict, by borrowing money from somewhere else."
Clinton added: "We depend on Japan, China, the United Kingdom, Saudi Arabia, and Korea primarily to basically loan us money every day of the year to cover my tax cut and these conflicts and Katrina. I don't think it makes any sense."
