This has probably already been discussed, but I somehow missed this:
Military chiefs gather in UK to discuss Ukraine peacekeeping force
This would not be a NATO op. It would be a "coalition of the willing" op that included NATO member states. The Brits and the French are
exactly the kinds of troops you need on the ground: capable, professional, and disciplined.
I served in Bosnia in the UNPROFOR days.The Egyptians in Bosnia were not the most capable. In fact, they spent the winter huddled around burn barrels trying to keep warm. They did not stop ceasefire violations. They were not even
aware of ceasefire violations in their sector.
What is needed in Ukraine are capable troops, with
a robust ROE so that, whenever someone steps out of line, the peacekeepers smack the crap out of them
instantaneously. Otherwise, why bother going? If you do not immediately punish violators, the situation wioll sprial out of control and the war start back, only this time with non-ERussian, non-Ukrainian peacekeeprs in the way.
Within BH Command when I was there in 1994, the British sent an LO to the Spanish Battalion (SPANBAT). The combatants (Serbs, Croats) used to take pot shots at the blue helmets all the time. The UN lost dozens of soldiers killed this way. The Brit LO rode around in a Warrior (Brit APC like a Bradley, but less capable). The combatants who shot at the Brit LO would get a burst of 25mm chain gun in return. Pretty soon, all the combatants in Gornji Vakuf learned
not to shoot at the Brit LO. A key lesson for any peacekeepers who might go to Ukraine.
