As with the the Iraq war, he's the ****er who started it all. He was the first to promise a referendum:
Blair promises: "We will put it [the constitution] to the British people in a referendum and campaign wholeheartedly for a Yes vote."
So how is that different to Cameron/May?
The world is dangerous right now, not simply for all the conventional reasons.
It is dangerous because Western politics is at risk of losing its way and its character. Just look at this Presidential election in the USA to see it.
Well so far the world feels a safer place under Trump than it did under Blair and Bush, Trump is up against resistance to most everything he does at home and abroad. Invading Iraq was the biggest loss of way and character by a British PM in my lifetime if measured in loss of life and chaos left behind.
Blair the hypocritical liar with a highly selective memory as usual.
