From thousands of years ago, governments have been on a fierce endeavour to build empires. From the Biblical days of King David, through the conquest times of Alexander, Napoleon and the recent history of British Imperialism, the agenda of setting up empires has been advanced by all means possible, leaders knowing that in order to give their citizens quality lives, some foreigners had to be controlled so as to act as markets for the produce of the controlling state, act as forced labourers for the controlling state or produce resources that could be consumed by the controlling state. This has not changed and it may never change!
Throughout history the trend has been that a nation is as great as the empire it controls. A century ago no nation could challenge British power.
