Varilla came to the White House and convinced Roosevelt that the best way to get around the Colombian Senate's obstinacy was to start fucking with Colombia's domestic politics in a big way. See, at the time, Panama was considering seceding from Colombia, and Roosevelt decided that in order to get what he wanted, he was going to have to become that country's anti-Lincoln and get some Panamanians civil-warring. When Panama officially announced that it's independence, Roosevelt sent the USS Nashville to block the Colombian navy from interfering. And thus an independent country was born.
The UN Security Council established the International Criminal Tribunal for Rwanda in 1994 following the Rwandan Genocide . Under the ICTR Statute, the link between crimes against humanity and an armed conflict of any kind was dropped. Rather, the requirement was added that the inhumane acts must be part of a “systematic or widespread attack against any civilian population on national, political, ethnic, racial or religious grounds.”  Unlike the conflict in the former Yugoslavia, the conflict in Rwanda was deemed to be non-international, so crimes against humanity would likely not have been applicable if the nexus to armed conflict had been maintained.
Violence between Buddhists and Muslims in Arakan State dates back many decades. The contemporary conflict can be traced at least to the Second World War, when the Rohingya remained loyal to the British colonial rulers, and the Arakanese sided with the invading Japanese. Clashes between Arakanese and Rohingya have occurred ever since. While both populations have faced oppression by successive Burmese governments after independence in 1948, governments in the predominantly Buddhist country have routinely persecuted and forcibly displaced the Rohingya population, altering the ethnic profile of Arakan State.
