Throughout history society has determined specific rules of engagement between adversaries in armed conflict. With advances in technology, from armor to in the Middle Ages to nerve gas in World War I to weapons of mass destruction in our own time, the rules have constantly evolved. Today, when killing the enemy can seem palpably risk-free and tantamount to playing a violent video game, what constitutes warfare? What is the effect of remote combat on individual soldiers? And what are the unforeseen repercussions that could affect us all?

How can you believe all this stuff? This is the number one question Catholics get asked - and, sometimes, we ask ourselves. Why We're Catholic assembles the clearest, friendliest, most helpful answers that Trent learned to give to people. Beginning with how we can know reality and ending with our hope of eternal life, it's the perfect way to help skeptics and seekers (or Catholics who want to firm up their faith) understand the evidence that bolsters our belief - and brings us joy.

Like author Simon Chase, many PMCs were once the world's top military operatives, and since retiring from outfits like US Navy SEAL TEAM Six and the UK's Special Boat Service, they have devoted their lives to executing missions too sensitive for the government to acknowledge.

Indeed, many view religion in general, and Christianity in particular, as unfounded and unreasonable. 6Norman Geisler and Frank Turek argue, however, that Christianity is not only more reasonable than all other belief systems, but is indeed more rational than unbelief itself.
