President of Argentina
Under the 1994 constitutional amendment, the President serves for four years, with a possibility of immediate reelection for one more term. However, unlike the President of the United States, in Argentina, a person may be reelected again after serving for two terms and staying out of office for the following term. So after serving for two consecutive periods, the president is not allowed to run for a third consecutive one, but may return for the two following elections and so on. There is no limit for a person to be a candidate if he or she does not win the elections.
Term limits in the United States
Thomas Jefferson mentioned that Washington retired after serving only two terms, without mentioning that Washington opposed the policy Jefferson was proposing. Crockett argues that Washington "did not intentionally establish the so-called two-term tradition; his departure was motivated by a desire to demonstrate that the country could function without him and to retire to Mount Vernon. He made no principled argument for limiting presidents to two terms, and in fact disagreed with Thomas Jefferson on this point." The "two term tradition" was created in 1807-1808 and it is often mistakenly suggested Washington had launched the policy. 
In 1861, the Confederate States of America adopted a six-year term for their president and vice-president and barred the president from seeking re-election. That innovation was endorsed by many American politicians after the Civil War, most notably by Rutherford B. Hayes in his inaugural address. Ulysses Grant was urged to run for a third term in 1876, but he refused. He did try to win the 1880 nomination, but was defeated in part because of anti-third-term sentiment. Theodore Roosevelt had already served over 7 years and in 1912, after a four-year hiatus, ran for a third term. He was violently criticized; indeed, he was almost killed by John Flammang Schrank, who was obsessed with stopping a third term.
