He has "accidently" dropped a few weapon caches to ISIS, his friends support ISIS(or have), and he aided Iran.
I have no knowledge of the Obama administration supplying ISIS. I acknowledge that they supplied Al-Nusra (at approval of congress), but not Daesh.
Iran does not
sponsor terrorism. Hezbollah, Houthis, and Quds Force do not engage in terroriosm. However, the Iranian military does oppress and terrorize minorities within their countries, such as Kurds, Baha'i, and Sunni.
You could possibly blame ignorance for my opinions, but if you do, please inform me.
Any list implicating Obama could not even come even close to surpassing the level of shit that the Reagan administration committed.
His administration committed hundreds of acts in dozens of countries all over the world. The whole entire Reagan doctrine consisted of financing questionable groups (some disavowed by the US today) and using the CIA to institute third world regime changes.
The Eritrean state alone is enough to put Reagan at the top.
