Blair's Iranian hostage dilema

So it has been proven that the service personnel on HMS Cornwall did stray into Iranian waters, according to defence officials. So is Tony Blair a liar?, a few days ago he said "It is simply not true that the personnel were in Iranian waters." Or perhaps he is guilty of leaping to the defence of the personnel too quickly?

I am still undecided as to whether or not the information is accurate.
According to a BBC report :" The UK government said the Iranians initially said the merchant vessel searched by the navy personnel had been at a point within Iraqi waters, before later providing a second, alternative position, within Iranian waters."

Blair has faced a difficult dilemma here, to show unwavering support for the personnel, or to focus on bilateral relations with Iran.

The situation has also taken a new turn with the appearance of the personnel on television. Faye Turney, the only female on board, read out a letter home, which commented: "We were out in the boats when we were arrested by Iranian forces as we had apparently gone into Iranian waters," the letter said. "I wish we hadn’t because then I’d be home with you all right now."

To me, her use of the word 'apparently' indicates to me that perhaps she is unsure about whether or not the boat was in Iranian waters, or perhaps, alarmingly, she could be trying to indicate to the UK government that she has been pressured into making the statement. This is situation is becoming a greater concern as it continues, and for Blair, a great dilemma. Iran will no doubt take advantage of its position, as if feel that such a situation is very advantageous for it, as recent rumours of a military threat from the US over its nuclear development has placed the country in a vulnerable position.

Today Jack Straw announced such action by the UK over 'that' issue was "Inconceivable". (Interesting timing). I think this is a perfect demonstration by Iran of its power over allied states.
