The USA -- reacting to a combination of war weariness, financial distress, and a veritable barrage of (often justifiable) criticism of the tenor or its actions -- has more or less quit being the de facto "world policeman." Since many (most?) cultures do not inherently respect the rule of law as something worthwhile of itself, and absent a policemen to encourage order, the result is all sorts of parties pursuing their agenda without much regard for the opinions of others. And why shouldn't they? It is logical to do so when you know that you can get away with it and that someone might change the policy back later on -- get while the getting is good.
