Ronald Reagan was quite the dove, actually. The only foreign interventions of note in his 8 years as president were the UN peacekeeping mission in Lebanon, which he pulled out of immediately as soon as things got too hot, and invading the tiny, practically-uninhabited island of Grenada. In private, he liked to talk about how much he wanted world peace and nuclear disarmament - he almost agreed to get rid of the entire US nuclear stockpile in his 1986 summit with Gorbachev.
His foreign policy was hardly good, just, or moral, but it was certainly above-average for 20th/21st century presidents.
Ahh yes quite the Dove indeed. he only just decided to arm Saddam, arm the Iranian's, so he could fund the Contra's, whose funding was made illegal since they were raping and killing women and children.....
