Conquest, war, famine, and death
It is said in the bible in the last book called Revelations
A check is a set of written direction which tells a financial institution or a bank how to use the money for paying someone. That someone is the person who the issuer of check owes the money. The issuer of the check will be the one who is responsible in paying the financial institution or the bank with the amount of money stated on the check. The check also serves as good as cash or it can also be a post cash payment to someone. It can also be served as a collateral to someone's liability.
This is an opinion question, but I believe that it is possible to seize political control over a country without oppressing the country's people. However, history has shown otherwise (Nazi Germany, British Empire) but we can use past mistakes to improve our future world.
