Hizbullah, Iran, and Syria

From their own standpoint, and from the standpoint of their own political interests, one of the biggest mistakes of the triangle is their aversion to going all-out against Saudi Arabia and its plots in the region.  Instead, they even prevented and muzzled any voices critical of Saudi Arabia from appearing on their media, while Saudi media were going all out against them.  The Syrian regime is still avoiding any critical comment against Saudi Arabia: it speaks of an external (and "known") conspiracy but refuses to identify it.
