Boris To Blame For Nazanin

Six years after it started, the Nazanin Zaghari-Ratcliffe affair has come to a close and she is safely back home with her family and all it took was for Britain to finally setle the £400m bill for an arms deal for British tanks dating back to the 70s which were never delivered.
The question being asked now is why was the debt not paid previously and the answer is because Russian oil is going to be less accessible as sanctions increase on Putin regime and other sources must be found hence the thaw in Iranian-British relations and the scenes of The British Prime Minister cosying up to an oil rich nation which is doing to Yemen exactly what Russia is doing to Ukraine so it's 'Hi, murderous dictators, can you help us out with this problem caused by that other murderous dictator'?.
It is unlikely that Nazanin or her family will be meeting the Prime Minister Boris Johnson anytime soon, it was his carelessness when he was the Foreign Minister which made her situation much worse, commenting that she had been in Tehran training journalists which only bolstered the Iranians claims that she was working against the Government and increased her sentence.
I am sure that the Government will have the brass neck to try and take the plaudits for her release but her husband, who has been campaigning relentlessly since she was taken prisoner, said that the fault lays squarely with the Prime Minister and his 'dismal failure', 'ignorance' and 'devastating blunder in 2017 when he was foreign secretary' and imploring they pay the long standing debt.
