Alternate strategies:
1. During the times of the ancient Greeks, the world was just as complicated and war torn as it is today. Sparta was the most powerful Greek city-state as far as infantry was concerned. But whenever an ally of Sparta was being attacked and asked for help, Sparta rarely sent troops. Most of the time, they would send just one man, a General. Upon arrival, the General would tell the ally that he was there to assume full military command, and that unless they did exactly what he said to do 100% of the time, he would simply get on a ship and sail back to Sparta.
This strategy was used when Athens decided to invade the island of Sicily and conquer it all for themselves. A single Spartan General was sent to aid the Sicilians, took charge, and using only the Sicilian troops (and few sent by other allies), he proceeded to destroy both invading fleets sent by the Athenians, as well as about 100,000 Athenian infantry. (The vast majority of the Athenians who surrendered were simply executed, or they were thrown into a deep rocky gorge, where they were removed and executed one by one.) It permanently ended the naval power and empire of Athens.
2. Or perhaps, we may consider the strategy of modern day France. They announced many years ago that they were almost never going to send troops anywhere, but that if an invading army attacked them or crossed their borders, they were going to immediately launch their nuclear arsenal against the attacking country. (France learned its lesson from its colonial defeat in Viet Nam, which we of course ingnored).
Just some thoughts.
