Starting from Top Left:

1. Former elected leader of Iran in the 1950s who wanted to take control of the nation's oil instead of BP, Britain got our President to authorize CIA to take him out and install the Shah, a brutal dictator.

2. Elected leader of one the South American countries who was also kicked out by the CIA and then a dictator was installed in the 1950s.

3. Osama bin Laden, whom the USA funded against the Soviet Union (russia) in the 70s, 80s. He later created the attack on the twin towers.

4. Guy who revealed that the CIA was importing cocaine from South America to fund stuff that Congress and the American people would not agree to (dirty money under the table). Not surprisingly he ended up with a "suicide" bullet to the back of his head.

Colin Powell, who stated that Saddam Hussein did in fact have weapons of mass destruction, letting US invade and destroy what was left of Iraq and thus created ISIS.

ISIS, which was created because the US invaded Iraq and Obama decided to fund Syrian "moderates" who wanted to take over Syria. They then turned out to be psychopaths.

Foreign policy blunder one after another

ISIS's existence has nothing to do with Syrian anti-government rebels. It was an offshoot of the Al Qaeda franchise created in the power vacuum of Iraq. When ISIS spread into Syria, the US started funding other rebel groups not realizing other sponsors included original Al Qaeda, Iran, Hamas, etc.

"Moderate rebels" may mean Libya, which still doesn't have a stable non-warlord government(s). Many nominally ruling coalition allies were just plain fundamentalist terrorists, and the CIA was covertly using the Benghazi mission as a staging ground. This may or may not have contributed to the lax security situation that lead to the death of the ambassador.
