Graham.
Graham prefers a strong America in order to prevent the world from becoming unstable. A strong America means fewer wars. Clinton, on the other hand, would continue Obama's ideological policy of aloofness and normalization of the relations with abnormal regimes, a policy that hurts America's allies, works to the benefit of America's enemies, and causes wars because the existing balance of power collapses. This makes Clinton the real warmonger.
No, strong nations are perfectly capable of participating in many wars in the delusion that they are 'defending the interests of [insert nation]" and "being a force of good (or freedom)". Wars make a country weaker, not stronger.
