What were the causes of the Rwandan genocide, and who was president of the US in 2018?

Here are the answers to your questions:

1. The causes of fighting in Rwanda are:

   • Ethnic tensions between the Hutu and Tutsi groups, exacerbated by colonial policies.
   • Political instability and power struggles.
   • Economic hardship and resource scarcity.
   • Propaganda and incitement to hatred by extremist groups.
   • The assassination of President Juvénal Habyarimana in April 1994, which served as a catalyst for the genocide.

2. No American President was elected in 2018. US presidential elections occur every four years. The last president elected before 2018 was Donald Trump in 2016. He was the sitting president in 2018. The next presidential election after 2018 was in 2020.
