The 27-year-old defender was due to play for Holland against England at Wembley on Wednesday, only for the game to be called off the day before because rioting in London was stretching police resources.
A coincidence has also denied the Dutchman the chance to play in the opening weekend of the season after Everton's match at Tottenham on Saturday was also postponed because Spurs
And while Heitinga is frustrated at being denied a lack of action, he fully backed the decision made by the authorities.
"It has been a strange week. On Monday morning we were in camp training with the national team and then on Tuesday after breakfast we heard the game was cancelled," he told evertontv.
"I wanted to play at Wembley against England but if you look at what is happening it is not good and hopefully it will be better soon.
"Everybody was looking forward to the Premier League starting and it was disappointing that this game was also cancelled.
"Our league will start next week and we can only wait until the whistle goes.
"We understand the decision. We have to let the police do their job and I hope everywhere is quiet and there's no more damage.
"We are professionals and the most important thing is that everything is quiet and good in the city centres of England."
Heitinga's sentiments were echoed by team-mates Tim Cahill, Phil Neville and Louis Saha, who used Twitter to express their disappointment.
Cahill, returning from international duty with Australia having scored against Wales on Wednesday night, tweeted: "If the game's called off then it's understandable due to sad events.
"It's more important that the people are safe as much as we all love footy."
Club captain Neville wrote: "Although I'm gutted it's the right decision in the circumstances.
"I'm in depression now - trained for six weeks for Saturday's game.
"I know its 100% the right decision but I'm going to sulk all day!"
Striker Saha added: "Game off vs Spurs. Surely for a very good reason.
"Hope the one who suffered from the warzone will recover quick. My prayers are with them."
