Answer:
I quite agree with Locke and disagree with him.
The theory of war according to John Locke is a state of destruction that brings about death of individuals and destruction of nations.
I agree with Locke that in a case whereby the life the citizens are threatened, then it's appropriate to use military force. An example is when the life of the citizens are threatened, using military force is appropriate.
Also, using military power isn't appropriate in a case whereby the citizens are engaging in free speech. There have been some cases whereby the citizens in a country will be engaging in peaceful protests and they get beaten by the military. This isn't appropriate.
In conclusion, depending on the situation, Locke's use of military power might either be appropriate or inappropriate.
