Prime Minister Theresa May and the leader of the opposition Labour Party, Jeremy Corbyn, have been pitted against each other on a host of issues but nothing has caught the popular imagination more than terrorism, as I discovered after recent interaction with students, teachers and social workers in Manchester. Terrorism has acquired urgent saliency after the Manchester bombing in which 22 youngsters, including children, lost their lives.
The tailwind would have been behind the Prime Minister in another era – say, when George W Bush, Dick Cheney and Donald Rumsfeld were embarked on full-spectrum global dominance before Lehman Brothers collapsed. Theresa May, alas, is mandated to unclasp one hand from Europe and attempt to clasp Donald Trump's with the other. But Trump is perpetually on a high wire act of unpredictable spins and turns. How to clasp that hand? His dizzying performances, most recently at the G7 and NATO summits, have caused even the dour Angela Merkel to throw up her hands. He is too unreliable; Europe has to fend for itself, she suggested.
