A lot of things.
1)Announce a clear warning, stating in detail her expectations and her demands.
2)Go to the United Nations, and claim restoration of the constitutional Order plus sufficient guarantees for the safety of the TCs including their protection from military units that would arrive from Turkey and be under the command of UN officers.
3)Ask that the governing of the RoC is undertaken by the UN for as long as it is required to have a stable state, including the disolving of all armed forces other than Eldyk and Turdyk.
4)Demand the application of a plan aiming at the disarmament of all GC and TC paramilitary groups.
Make it clear that if nothing of the above would apply or in case they applied they were not effective, that she would intervene, to solve the problem via partition.In fact all these could be done long before 1974.
The aim however was different all along.It was to make the situation as bad as possible plus have a legal excuse to invade. While the situation was much worse in 1963 and in 1967 nothing happened because the legal excuse was missing.In 1974 the situation was almost normal. The coup and Sampson gave the legal excuse ready in the plate...
