In his quote he was talking about how, he was proud, that while he was president he didn't have to send any troops into war, or no other territories tried to take over some of the US' for the fact of the matter that he tried to keep it as peaceful as he could while he was president. I think his accomplishments were very spectacular, To this day no other US president has been able to do that. According to some US citizens, he was the "perfect" president, when it came to many things, such as war. Many people such as myself look up to him for the things he has done, I don't want to steal his glory, I just want to have my own for my own reasons.
Hope this helps!
