No, most of the largest wars have been fought over issues other than religion. Religion has been the primary reason or a secondary reason for many wars, but taking some examples affecting America:
Iraq - energy, depose a dictator [Edit, OTR: The Bush Doctrine was based on a Christian vs. Islamic fundamentalism. Fighting for Christian "values" was a major part of this conflict.]
Vietnam - opposition to communism vs. Vietnamese nationalism
Korea - opposition to communism and aggression vs. desire (on both sides) for national unity under one government.
World War II - control aggression vs. militaristic / fascist expansionism
World War I - Many complex reasons dealing with colonial control, expansion of trade, free shipping, ultra-nationalism.
Spanish-American War - lunacy, combined with conflicts over colonialism
US Civil War - slavery, secession, economic power
Mexican War - expansionism (by US) and territorial control (by Mexico)
War of 1812 - free trade, rights of seamen
Some of the other really big, nasty wars - Napoleonic wars - French expansionism and colonialism, ultra-nationalism.
South American independence - nationalism vs. colonialism
Russian revolution - oppression by royalty
There are lots of counter-examples, but the largest, most destructive, and most deadly wars in history had little or nothing to do with religion.
One huge counter example is found in the India - Pakistan - Bangladesh conflicts and in the internal on-again off-again issues with Sikh violence. In these conflicts religion mixes with ultra-nationalism to generate terrible losses. The Serb Orthodox vs. Kosovo Muslim conflict was another smaller counter-example.
Religion often finds little niches within wars, like the German 'Gott mit Uns' (God with us) on belt buckles and other military gear, which causes anti-religious groups a chance to seize 'evidence' of the destructiveness of religion. American sniper scopes have New Testament Bible verses inscribed on them (a practice which was ended in 2009), again causing anti-religious people to declare that war and killing were caused by religion.

Yes, their were many wars in the 1700s. Most wars in the 1700s were fought over power/control over a colony by the European Colonial powers. Other wars were fought for other reasons, i.e. The American Revolution was fought to gain American independence, and etc...
The US fought three wars to obtain land: 1. Indian Wars (1620-1890) 2. Mexican War (1846-1848) 3. Spanish-American War 1898
The two western countries whose rivalry have caused several wars would be England and Germany. They have fought three major wars in the last 150 years.
America fought on the Allied side during both World Wars and now they are one of the major Western Powers.

major wars fought by U.S.
Most of the naval battles of the Punic Wars were fought over the Mediterranean Sea, although that was not what the War was fought over. The war was fought over places like Corsica and Sardinia, and Spain.
Yes there can be peace without religion. Too many wars have been fought because of religion.
