Just like Vietnam of old, Mali is a former French colony and there are 3,000 French citizens living there, plus thousands more living in neighbouring countries.
Edit to add: The United States is planning to provide logistical help to France, likely including satellite imagery and intelligence sharing, plus military transport and perhaps drone surveillance.
THIS IS FOR NOW.
Let the Europeans clean up their mess. Africa was the playground of the Brits, French, Dutch, Spanish, and Portugese. They @#$%$ it up, they need to clean it up.
Mali matters more to them than it does to us. These African countries also need to step up and clean their own house also. We cannot continue to send our best and brightest into every shiitehole to clean up the messes of others.
