It is clear we cannot leave Britain's defence and security in the hands of the EU. A vote to Remain will validate this lie it is the EU which has maintained peace in Europe. Whether or not Trump is elected President in America will not matter in the end. America will see the EU as the future of Europe, and NATO as expensive relic of a bygone age.
The EU has already been buffeted by the Eurozone and migration crises; one more major shock to the system could well mark the beginning of the end. In the words of David Cameron: 'Can we be so sure that peace and stability on our continent are assured beyond any shadow of doubt?' Like the prime minister, I would never be so rash as to make that assumption.
Refugees want above all to be safe, and to have some hope that they can build a new and better life for themselves and their children, either in a new home or back in their old home once the conflict is over. Europe's voters want their governments to show that they are on top of the crisis, not paralysed into inaction.
Tyrannical and thoroughly disagreeable though he is, Mr Putin stands for nationalistic pride, a crucial buffer against the perils of American foreign policy and a determination to defend a revived Russia on the world stage, and her citizens abroad. Three things I respect, and three things a shrinking world desperately needs.
Already the UK is kept more secure and has a stronger leadership role on the global stage because of our military co-operation with Europe. If we are to continue to reap these benefits though, we cannot countenance turning our back on the EU, pulling up the drawbridge and going it alone. We have to engage more widely with political elites in our partner countries to make sure that we build their support.
Just five years ago we had a Strategic Defence and Security Review which proposed armed forces configured for an age of austerity when most of the threats we faced were, at the very least, containable. We were pulling out of an expensive war in Afghanistan... Just five years later we live in a very different world.
