We have no shortage of doctors here. MSF is an organization with a particular mission, and they stick to it. They have established infrastructures in countries that need them on an ongoing basis. The U.S. is quite reasonably beyond the scope of their mission.
As an otherwise MSF-supporter, I have to ask you "why"?
What's the difference between a natural disaster in Banda Achea and another in New Orleans/Biloxi?
Don't bother to answer, the difference is objectively zero - and you know that - whereas MSF/DWB (and you) are taking an egregiously political position, in lieu of human lives.
Bastards.
MSF is an organization that always needs funding. Whoever runs it is dumber than a post in a democrat's back yard.
If MSF said, "sure we'll help," then the charitable coffers of the USA would have opened to them in the future. Now they will starve, when it is remembered that they could have helped. Additionally their names will be put on the Persona Non Grata list of the USA Dept. of Staff and the War Dept. I can hardly wait when they later want into a theater of war,or theater of aid commanded by the USA. They will simply be told they are not needed.
Dumb and Dumber.
Je ne sais pas quois d' autre!
