Since 2017, relations, particularly in terms of intelligence, have multiplied between countries in the region united within the "Koundalgou" operation. Leader of Togolese opposition, Paul Dodji Apévon, of the Democratic Forces for the Republic, believes that this collaboration must be stronger: "I know they are consulting with each other, but I think they need to do even more so that there is truly genuine solidarity. There must be a real commitment from governors to move toward what we can call regional solidarity and against this phenomenon."

Member of the ruling party Union for the Republic, Atcholi Aklesso, calls for national unity after this attack in northern Togo. He also wishes for better collaboration with neighboring countries and refuses to comment on instability in the sub-region: "I will not presume to comment on the domestic politics of other countries, but the evil that is there and affects all our countries, I believe that is the subject. Our states should, and they are already doing so, organize themselves for the fight."

Premonitory statement? On April 16, President Faure Gnassingbé declared: "Terrorism can no longer be seen as a problem of Mali, Niger or Burkina Faso. This is becoming a problem for ECOWAS." Faced with an enemy that has no borders, collective mobilization of states is now essential.
