In a must-see "On The Record" interview tonight, Greta Van Susteren spoke to former President George W. Bush at his childhood home in Midland, Texas.

The 43rd president discussed his new book about his dad, "41: A Portrait of My Father," Vladimir Putin, the rise of ISIS, his brother's possible presidential run and much more.

Watch part one of the interview above and parts two and three below.

"It's not an objective analysis of President Bush. It's a story about an extraordinary man, who in my judgment is the finest one-term president our country's ever had."

"He was president when the [Berlin] wall came down ... as he said, 'I'm not going to dance on the wall.' ... He didn't want to brag. It wasn't about him. It was about the success of an ideology prevailing over another ideology."

"He's a gentle soul, and he cares about the other person a lot. He's got a wonderful sense of humor and he's comfortable, as they say, in his own skin."

"His mother raised him not to brag, which can be a liability in the political world, because you've got to talk about yourself and explain the successes you've had."

"Jeb, he's wrestling with the decision to run for president. He's seen his dad, he's seen his brother. There's no pressure anyone could put on him ... Only he can make the decision."

"During my presidency, Vladimir [Putin] began to act in terms of 'zero sum politics' ... either I win or you win, neither of us can win together."

On ISIS beheading American hostage Peter Kassig and President Obama's goal of "degrading and destroying" the terror group: "Murdering the innocent to advance a political objective is and always has been evil. So let's just hope the president meets the goal he outlined."
