At this stage, Paul Pierce and Kevin Garnett have made like the last Japanese soldiers on Iwo Jima, refusing to give up the war.

That’s how the two former Celtics continue to regard their former teammate and current Heat guard, Ray Allen.

“They haven’t spoken to me,” Allen said before last night’s game against what remained of his former team. Allen played 24 minutes and had five points with three assists as the Celtics stunned the defending champion Heat, 111-110.

Allen admittedly is hurt, because he doesn’t understand the difference between their trade out of Boston last summer and his decision to leave two years ago. Deep down, Allen believes Pierce and Garnett determined their own fate.

“For them to be so upset with me is disappointing because of how everything happened,” Allen said. “That banner in 2008 is still going to be there, and we’re still going to be tied to it.

“Look, I have a feeling they were in the same predicament I was in this summer. Even with Doc (Rivers), he had to make a decision that was best for himself. I was in the same situation. I’m happy they were put into the same situation as I was. Anytime you get traded there’s no telling where you could end up. They’re in a situation now where they can contend. Kevin had to make that decision, and that was the predicament I was in.”

Allen laughed when asked if Rivers, whose Clippers lost to the Heat last week, has reached out. Rivers, like Garnett and Pierce, was also critical of Allen’s move.

“Doc talked to me like I was still on his team,” Allen said. “I got heavily criticized by each one of them the minute I left. They were upset. But the writing was on the wall for us. (Celtics management) was saying, ‘Hey, we’re moving in a different direction.’ And each one of us had to make that choice. Where can we go to be successful and continue to play good basketball.”

That’s why, at the time, Allen felt he was persecuted for his decision.

“I did think that,” he said. “But I was curious to see how it was received in the NBA and the people in Boston. In my opinion it was the same scenario. I wasn’t upset with any of those guys, because it was their right. You have to make the choices you feel are best for your situation. That’s why I was so disappointed in the reaction to me, because those guys know what it takes.”

When it was suggested to Allen the public perception of his decision to leave was different — Pierce and Garnett were traded and he turned down a higher contract offer ($6 million per year) to sign with Miami for half the money — he disagreed.
