We would all like not to have to keep coalition forces in Iraq and Syria. We hope that these countries become stable again and capable of moving toward becoming pluralistic democracies. But we're far from that. In the meantime, we have a commitment of several years to honour. Our goal isn't only to abolish this horrible terrorist group, but also to ensure that it does not re-emerge later through another group and under another name. So we need to create conditions conducive to lasting stability and peace.
