On Sunday, Terry sensationally quit England less than 24 hours before the FA hearing into the racism storm that erupted over a clash with Anton Ferdinand at Loftus Road last October.
He said he had taken the decision on the eve of his improper conduct hearing because his position with England was now "untenable".
"As he proved at Euro 2012 and against Moldova earlier this month, he [Terry] remains this country's best defender," wrote Wright in his column for The Sun.
"It's a shame he's called time on international football.
"This is a hasty decision and he's done it for all the wrong reasons.
"Even if Terry, 31, gets an FA ban following his incident with Anton Ferdinand, he should have been able to separate the two and carry on playing for England.
"In the past he has carried on regardless of other things so I don't know why he has not been able to do the same now.
"He cannot blame anyone else, though.
"What came out of his mouth was the problem.
"And I absolutely guarantee Terry will regret this decision to quit."
Wright went on to paint a picture of Terry sitting at home watching England in their opening FIFA World Cup 2014 match in Brazil - and wishing he was there.
He wrote in The Sun: "This Ferdinand saga will seem a very long time ago [by 2014] and Terry will think to himself 'Why did I do that and retire?'
"In four years time, the European Championships will be staged in France and Terry will be 35.
"Injury-permitting, he could - potentially - still be a useful member of the squad.
"Terry knows he will be missed in this current England team and he's been an outstanding servant.
"Even in his last game, against Moldova, he showed real courage by refusing to leave the pitch with 20 minutes left, despite being injured.
"England boss Roy Hodgson had used all three of his substitutes but Terry was determined to avoid seeing his team reduced to 10 men, even though England were cruising. I'm not having a go at Joleon Lescott, Gary Cahill or Phil Jagielka.
"But against Ukraine at Wembley, without Terry in the team, I thought we looked a bit vulnerable."
On Monday, Terry and Ferdinand were present at the disciplinary hearing over allegations hthe Chelsea skipper racially abused the QPR defender.
Ferdinand gave his testimony to the independent panel at the hearing at Wembley Stadium with Terry in attendance to hear the evidence against him.
