No he isn't.
He said she started a war to win an election. She didn't. That is what we are debating here, nothing else.
She'd be genius if she could have planned all that, albeit an evil one. The idea she deliberately manipulated events to encourage the Argies to start a war is ludicrous. Did she act like an opportunist and wrap herself in the flag, of course she did, she's a Tory. Did it help her win an election, of course, she's a Tory.
Did she start a war to win an election - don't be ridiculous that's not how things work.
As usual with Chesh he has a version of the facts, just not quite the right ones. You are making the mistake of accepting his lack of precision.
In my view - In their first years in office they were cutting everything and someone - way below PM in rank - decided the South Atlantic infrastructure could go to meet budgets. The Foreign Office were talking to the Argies about shared sovereignty. I can well believe the Argies thought this all meant we were a pushover, especially with a woman was in charge. Then when they invaded, first she HAD to fight or she would have been dead meat politically, as a Tory PM, and then of course she used the armed forces performance to help win the next election.
Chesh will think the above means I am agreeing he's right. That's because he's not very good at precise thinking. He's wrong, something vaguely similar to what he asserts happened, did happen, but just not what he says.
