Can the Gulf Stream be used as a weapon for war?

The Gulf Stream could be more powerful that many nuclear weapons exploding at the same time. 

We know that the Gulf Stream controls temperatures in Europe. By redirecting the Gulf Stream or making the Gulf Stream collapse, NATO will be finished and most of Europe will be neutralized for many years to come with massive loss of European population.

By neutralizing Europe - or in other words if Europe ceases to exist - the balance of forces across the world can suddenly be altered for good. 

Every world war is similar in some ways to the previous world war and also different in some ways. In 1939, the French believed that their Armed Forces were marvellous as they were the victors of 1914-1918. They fought and lost World War Two using the same conventional strategies of World War One with no communications, no proper command, in a war they believe was going to be like World War Two. They event sent the biggest numbers and the most capable forces towards Belgium and were caught up in a bag, leaving the way open for German forces to advance to Paris with little resistance.

Today, the world relies on nuclear weapons. Are nuclear weapons the biggest threat. Climate is the biggest threat. Climate is more powerful than nuclear weapons and has more lasting consequences. What can change climate dramatically? The sea. The sea is a weapon for war that can destroy hundreds of millions very quickly and neutralize enemies for many years to come. If the sea were to be used for war, Europe would be no more.
