Second terms can often be productive times for US foreign policy, largely because presidents cannot seek a third. George W. Bush, for example, used his second four years in office to fix mistakes made during his first (his second-term team was busy).
第二个任期对于美国对外政策来说通常是富有成效的四年，这主要是因为总统们不能寻求第三个任期。比如，小布什把他的第二个任期用来修正第一个任期中犯下的错误（他的第二任期团队可忙坏了）。
