The truth is that ISIS increasingly DOES have power over us because its own ultra-violent campaign has made many people now deeply fearful of going about their normal lives in the way Obama suggests.

What I suspect the terrorists are really thinking is that if the U.S. president is so relaxed about them blowing up Brussels that he can go to watch baseball immediately afterwards, then they have nothing to worry about and can continue, with impunity, committing massacres on people also ‘going about their normal lives’.

I am reminded of Obama’s reaction when ISIS beheaded American journalist James Foley.

He made a quick speech saying how dreadful it all was, then, just seven minutes later, he was filmed teeing off on the golf course and laughing with some mates.

That was a disgrace, and so is this.

By stark contrast, France’s Prime Minister, Manuel Valls, declared; ‘We are at war. We have been subjected for the last few months in Europe to acts of war.’

Absolutely right.
