Generate text that refutes this claim: PMCs provide a service that may be otherwise unavailable.  Many nation states have achieved sufficient unity to rely on their own armies but for those which cant, mercenary forces provide an invaluable and possibly only mode of protection and security. British Foreign Secretary Jack Straw believes that in an era of “small wars and weak states” mercenaries have a “legitimate role” (The Economist, 2002). Mercenaries may be the only way of providing short term security guarantees to allow a government to establish itself without relying on warlords or one side of an ethnic conflict. This could be the only way out of a pattern of coup and counter-coup. Recruiting local mercenaries also has the benefits of reducing transportation costs, instant readiness as well as any knowledge of the local politics, geography and customs which may be highly valuable to a security force. These local recruits may be less inclined to share this information with a government force.

The use of mercenaries is counterproductive for unstable states. By relying on hired mercenaries weak states encourage private competition rather than reinforcing their own nascent armies. The emergence of powerful local, as well as international, mercenary organisations frustrates the ultimate goal of securing a state monopoly over the use of force. There are many cases where mercenaries have remained in a region long after their official contract ended in an attempt to exploit regional instability in order to further a particular ideological cause or reap financial reward. Colonel Bob Denard fought vaguely “against Communism” in Africa and attempted to overthrow the government of the Comoros Islands off Madagascar on four separate occasions. Similarly, Colonel “Mad” Mike Hoare tried to topple the government of the Seychelles in 1981, arriving with 43 mercenaries disguised as rugby playing members of a beer-tasting club named The Ancient Order of Froth Blowers. Furthermore, PMCs may be helpful in resolving conflicts in the short-term, they are not viable solutions because they do nothing to actually solve the problem in the long-term.
