Thomas Jefferson said "peace, commerce, and honest friendship with all nations, entangling alliances with none..." He believed this was an essential pillar of government. I believe he was right then and now.
That's just too damn reasonable.
Qui desiderat pacem, preparet bellum. Vegetius
"To be prepared for War is one of the most effectual means of preserving peace."
President George Washington
first annual address to Congress, January 8, 1790
In pace, ut sapiens, aptarit idonea bello. Horace

The most dangerous assumption is the one that is not realized as such. An assumption that is realized can be strengthened and improved in detail if it is true, and rejected if it is false. The one that is unstated offers the danger of not showing its full glory if it is true, and not offering itself for rejection if it is false. There is an often unrealized assumption that there are ultimately some situations where violence is the only way out (IE where God can't or won't use any other means), and furthermore that the choice is between violence and inaction (no other alternatives). Stating that it is an assumption neither proves nor disproves it, but does bring it to light - to consider and judge as an assumption.
The new law is to love your enemy as yourself, and to forgive the one who injures you seven times seventy, as per Matthew 18:22.
To establish peace, you do not merely ensure a lack of physical violence (particularly not through intimidation at your own superior capability for violence - "peace through strength" destroys what it wishes to establish), but rather work to remove all traces of hatred and injustice. Peace is not an absence, but the presence of love.
"The greatest of these is love." I Cor 13:13 Establish love and there will be peace.
