Yet it isn't fair to people that rely on such assistance to drop it without a plan to substitute the assistance provider. It was all done overnight. One day you had outposts serving people in need, the other they had their doors closed.
So don't act like the world should be thankful for all the US has done when it pulls the plug in such a way that is maybe more devastating than having done nothing, because at least nothing would have left the spot for someone else to have risen to the occasion. Maybe this time though without using people's basic needs to create a political tool to be used opportunitistically.
The world has never been thankful for the positive things the US has done. The only thing it ever garnered were the briefest of superficial nods. China gets drastically more respect with their approach than the US ever has, while doing a tiny fraction of the good.
The US saved tens of millions of Russians from starvation a century ago. Culturally they have absolutely no clue about that, they're entirely oblivious in terms of their own history. The good deeds never garnered the US any positive credit. Only the bad deeds garner the US bad credit aplenty.
