"These boys have given up some things to play for England and that's a huge commitment.
"I'm looking forward to playing alongside them. We all know the rules are different now and the other nations do it, so why can't we?
"It's a really exciting squad. It's going to be a good team to play in. Get this right and there is a big chance of success."
In addition to bringing together different nationalities, England coach Steve McNamara has had to deal with tribal issues closer to home, with the verbal spat between St Helens forward Jon Wilkin and Leeds prop Ryan Bailey overshadowing his squad selection.
The Super League grand final combatants broke the ice before going into camp and Leeds front rower Peacock is confident the bad blood will not spill over into the preparations for the Four Nations.
"We've had a clear-the-air meeting," he said.
"It's time to put club colours behind you and put the red and white of England on.
"They have come together and spoken with each other.
"Rugby league is a confrontational sport. There are players in the squad who might not like me that much when I'm playing for Leeds and I could say the same about some of them.
"But, when I play for England, they're my brothers and I want to play as well as I can for them and vice versa."
Peacock has led his country since 2005 and, after proving his fitness after an eight-month layoff with a serious knee injury, which forced him to miss the 2010 Four Nations, was always likely to regain the captaincy.
"It's not something I take for granted," he said.
"There are strong candidates in the game at the moment and, when Steve rang to tell me the news, I was over the moon."
