The very famous person who said, "The most successful war seldom pays for its losses" was Thomas Jefferson. Jefferson used these words in a document (some correspondent) he sent to Edmund Randolph, the seventh Governor of Virginia and a delegate from Virginia, who attended America's Constitutional Convention.

Historians and political scholars tell us that Jefferson had a very specific point to make. He didn't want America to listen to false ideas to persuade the country that it was in its best interest to go to war. "Costs of war are high and the country's money can be put to better use." This was Jefferson's bottom line.

When put into humanitarian terms, Jefferson held: "The evils, which of necessity, we face are sufficiently numerous and encompass our lives each and every day. Why should we add to them (the evils) by voluntarily distressing and destroying one another? Peace brothers, is better than war. In a long and bloody war, we lose many friends and gain nothing. War is an ultimate cost that helps mostly the greedy!"
