A former President of a country in East Africahas been living in exile in Dubai.He flies to the US for a cancer operation and while here, is served with a summons for two lawsuits filed by U.S. residents who were former citizens of that East African country during the ex-President's tenure.

The lawsuits allege universal jurisdiction over the ex-President.

The first lawsuit's basis is that the defendant ordered the seizure of all farms owned by white or Asian people, regardless of the nationality of such people, thereby violating the UN Charter on Human Rights.

The second lawsuit's basis is that forces under his direct command committed violent crimes and murders against a specified group of people, for political purposes.

What defenses might the ex-President's counsel seek to use -- and what is their likelihood of success?
