Is Britain due to lead the free world?

With Trump recently pausing aid to Ukraine, at a time when Russia continues to advance over Ukrainian territory, the title on who leads the free world is starting to loosen up.

In unprecedented moves, where economic sanctions are slowly being lifted on Russia as Trump continues down the war path of placing tarrifs on all of his allies, it seems as though alliances that work against our interests are being forged in front of our very own eyes.

Will it be Britain, once again, at the forefront of upholding European liberty if the USA leaves NATO - a complete betrayal of her allies, or will it be somewhere else?

In 1945 we had the British Empire and US support, and even then, barely scraped by.

Where do we stand now?
