What did political philosopher John Locke believe allowed a government's chief executive to stretch a nation's laws for the public good?

john Locke's publication called his Second Treatise of Government allowed for extraordinary powers for a government's chief executive to handle military emergencies. He wrote that a legislative body would be too slow to react to a dangerous military threat. In such a situation a nation's top executive should have extraordinary powers to use force to save a nation from great harm.
