All of what you say is true. But the Obama administration hasn't restricted their services to the Sinaloa Cartel.
There is mounting evidence that Hillary's State Department has been busily running weapons (military hardware, in particular) to the Zetas -- via Honduras and via a front purchasing agency in Dallas.
Further, a third customer has recently been revealed -- employing straw purchasers under ATF surveillance in Indiana. This is how the makings for over 2,000 grenades ended up in the hands of La Familia de Michcoacana.
It seems apparent that the Obama administration has been arming virtually ever drug-smuggling operation in Mexico.

“What isn’t apparent is exactly what the intention was...”
If you research the “Reichstag Fire” and “Gleiwitz Incident” of the Nazis, the intention becomes crystal clear.
Both of those bogus operations were examples of how evil fascist regimes attempt to destroy their opposition by using nefarious conspiracies to sway public opinion to their side.
