Generate text that refutes this claim: PMCs are untrustworthy  The possibility of mercenaries pulling out will always remain a risk. PMCs are not fighting for their own country so they can never be threatened with a charge of desertion. PMCs are motivated by money and do not have the interests of their employer at heart. Loyalty is given to the highest bidder and is therefore delicately balanced. “The fact is, they have no other attraction or reason for keeping the field than a trifle of stipend, which is not sufficient to make them willing to die for you. They are ready enough to be your soldiers whilst you do not make war, but if war comes they take themselves off or run from the foe.”(Machiavelli, 1515) Machiavelli considered that it was mercenaries that ruined Italy much as they are now doing in Iraq and Afghanistan.

It is in the interest of PMCs to fulfil their contractual obligations to ensure future contracts and avoid the reputation of being treacherous. While PMCs are often considered to be untrustworthy there are very few examples, if any, of them actually running away or switching sides since the end of the cold war.
