If WWI and WWII never occurred, would European empires have been allowed to continue at full size to today?

Since World War I and World War II were the main factor in the crumbling of European empires due to a complete lack of effort, infrastructure, army, or funding from Europe to the colonies? Since World Wars I and II also caused Britain, Netherlands, France, etc. to have less money due to spending to rebuild buildings, get food, provide housing, etc. If World War II just never occurred altogether, would Britain have enough money, combat, and effort to have the British Empire exist at full size to today? Would India still be under British rule well into 2010, as well as Rhodesia, Kenya, West Indies, Malaya, Singapore, etc.? Also the same for the Dutch Empire, French Empire, Belgian Empire, etc. Also if World War I and II never existed colonies who fought for the mother European country could not use an excuse to say they fought for the mother country and so deserved independence in return.
