Now it is official

Earlier in the week here at CompHyp there was a thread titled Declaration in all but name.

Now it is official.

Sudan declares war on South Sudan:

Sudan's president, Omar al-Bashir, Thursday declared war on South Sudan, vowing to topple its government.

We've seen some similar conflicts recently; Ethiopia-Eritrea have a persistent border conflict, but... that's not being fought over a series of oil fields that are *vital* to the wealth of both parties.

This fight is going to be ugly.
