You really are delusional aren't you ? As I Christian I'm embarrassed to see that your name is christjesus. Could you please keep your mouth shut and not make the rest of us look bad.

The American founding fathers were very divided on many things. Some of the founding fathers such as Alexander Hamilton wanted this nation to become a Kingdom while others like Thomas Jefferson wanted the United States to become a Republic. Religion was no exception. While there was secular founding fathers like Thomas Paine, I think it is fair to say that a majority of them were followers of some form of Christianity. If by secular you mean separation of church and state then yes they intended it to be a secular nation. If you mean secular as in secular culturally then I would assume many of them would oppose it.

Yes, If it is in the national interest of course. For example if a nation is at war and the enemy army has a very capable commander which is of great importance to the enemy, then the government should do everything it can to eliminate this threat. However assassination is not something which should be used lightly. Assassinating foreign leaders is a very serious action which will not be taken lightly by other governments. A government should never assassinate a foreign leader who they are not war with simply because they don't like the way the leader runs their country.
