Several steps here..
1) The protests start, they cannot be controlled
2) The government send in the troops to sort the protests out
3) The protestors start to fight back, people are dying
4) The world asks them to stop, they refuse
5) The world looks to put troops on the ground to prevent it happening, they need the UN backing for this. Meanwhilst the fighting still goes on.
6) The UN backing is given, a ceasefire is made. UN troops move closer on hold.
7) The protests return, larger in size this time. The police try to hold things back.
8) Things cannot be contained by the police, armed force presence is needed to hold the country.
9) Fighting starts again.
10) UN move in.
I fully see now that we are at Step 6, which has taken 4 weeks to reach this choice. I can see the protests gathering momentum over the weekend, and us reaching steps 7 & 8 by the end of next week. Maybe Fri/Sat.
