That was President Theodore Roosevelt. However a little back story on the Canal is that the US government actually covertly started and funded the Panamanian Revolution which separated Panama from Columbia and in the end the US forced Panama into giving up the land that would eventually be the Panama Canal however the US covered their tracks and formed an agreement with France to make it seem as if France had bought the land so it was all legit on the international scene then France handed it over to the US who completed the construction of the canal. <span />
There was a lack of support for rebellions to gain independence.
This wasn’t much but I hope it helps some
Slavery tolerated because of "necessity" means that you do not really want to do it, but you think you must do it. An example is when you have a farm and you need people to work on it. The trouble behind this scenario is that your farm isn’t making money to pay your farm helpers their proper wages, so you resort to slavery. In this case, you do not need money for salaries because your farm is doing well to keep your slaves clothed and fed.
Slavery affirmed as a "moral right" is when you think it is your right to be the master and the slaves deserves to be slaves.
The Reformation created division within Europe. In Spain most people were Catholic. In the northern countries most people were Protestant. The Holy Roman Empire was a patchwork of small kingdoms, some Catholic.
