Buhari stops military war militants

I think there may be some confusion here. President Muhammadu Buhari, the current President of Nigeria, has not stopped military war against militants. In fact, the Nigerian military has been engaged in various conflicts against militant groups, including Boko Haram and the Islamic State West Africa Province (ISWAP), in the country's northeast region.

Boko Haram, a terrorist group, has been responsible for numerous attacks and kidnappings in Nigeria, Cameroon, Chad, and Niger. The Nigerian military has been fighting against the group since 2009, and while there have been some successes, the conflict remains ongoing.

ISWAP, a splinter group of Boko Haram, has also been involved in violent attacks in the region. The Nigerian military has been working with regional forces to combat both groups.

It's possible that you may be referring to a specific incident or development that has led to a temporary ceasefire or reduction in hostilities, but I'm not aware of any information that suggests President Buhari has stopped the military war against militants.

If you could provide more context or clarify what you mean by "stops military war militants," I'll do my best to provide more information.
