Washington (CNN) Former Secretary of State Colin Powell on Sunday contrasted the foreign policies espoused by President Donald Trump with those of late former President George H.W. Bush, saying the current withdrawals from international treaties are "terrible mistakes, which we will regret."

"Now, there are a lot of people now saying, 'Well, let's -- we got to get out of this treaty, we got to get out of that treaty,'" Powell said. "Bad, terrible mistakes, which we will regret, because they don't make sense."

In an interview with CNN's Jake Tapper on "State of the Union," Powell, who served as chairman of the Joint Chiefs of Staff under the 41st president and as secretary of state under his son, former President George W. Bush, gave as one example Trump's decision in October to withdraw from the decades-old Intermediate-Range Nuclear Forces Treaty with Russia, citing Moscow's violations of the treaty and China's missile arsenal as reasons for the move.

"Well, the Soviets -- the Soviets have been cheating on the INF Treaty, so let's get out of the INF Treaty," Powell said. "Oh, good, you do that and guess what? The Soviets aren't cheating anymore, because there is no treaty to cheat. It doesn't make any sense. But that's the kind of thing we're doing."

"Climate change, so many other areas where we are not demonstrating the kind of inspirational, broad-based leadership that we saw under Bush and (former President Ronald) Reagan," Powell said.
