No, its never wrong to change ones mind when the evidence shows one was wrong in the first place.
But Badenoch called for UK military involvement, she wanted UK strikes on missile sites, as did Farage, that is military involvement and is offensive in nature... how is it not, its just twisting words to pretend that flying bombing raids over Iran is defensive, Iran wasn't launching drones and missiles pre the US attacks.
To deny that is stupid but then Badenoch (and her supporters) are, she has no policies, no views other than to oppose... if Labour said they'd cut taxes, Badenoch would say they need to go up, she is also quite nasty in her attacks on Labour, go for the policies, sure but she makes it personal.
She leads a party that should be far ahead in the polls against a struggling Labour Govt, yet Tory polling is stuck solidly below 20%.
Thankfully though, she'll lead the Tories to their demise.... silver lining!
