Trench warfare

We have been at war for half of my lifetime, nearly all of my daughter's lifetime. It is our state of being. Political elites speak only of more of it, as if proposing a hike in Social Security benefits. No one (credible) says, let's just get out of the Middle East.
In many locations there would be near-constant bombardment from the enemy artillery. Snipers were omnipresent. Many a new man on the front line also learned the hard way that snipers were ready at all times to punish those foolhardy enough to peer carelessly above the parapet.
In the First World War, the politicians and monarchs were mostly content to "let it bleed" rather than be innovate enough to bring the war to a military or diplomatic end. We are once again in trench warfare.
