The Vancouver Whitecaps striker admits that he may never play at a major finals but insists that he has no intention of walking away from representing Scotland at any time
The 33-year-old's chances of playing in a major final appear to be over after his country's poor start to World Cup 2014 qualifying, which led to manager Craig Levein being sacked.
With Steven Fletcher back in the national team setup, Miller was dropped for the away defeats to Wales and Belgium in October but he is adamant that he will not withdraw from selection.
"I'll be 34 towards the end of this campaign," he told reporters. "It probably will be [the end of my international career], I imagine, even from a manager's point of view.

The former Rangers striker admits that he felt frustrated at being left out of the national side but accepts the decision, declaring: "I love playing for my country, it means a lot to me.
"I will always come as long as I'm selected. I was disappointed, of course I was, I was disappointed with the other 10 lads who weren't playing.
"I was really disappointed after scoring in the previous game and I always want to play. Craig wanted to go down a different road and we had a chat about it, and I just had to accept it. Fletch has come in and he was on fire at the time, playing in the Premiership and scoring goals.
"It was still hard to take, I still felt I should have played. But the manager felt Fletch was the right man for the job and you just have to accept that and be ready to play a part if called upon."
