The U.S. and most other countries have political structures with a subtle and dangerous bias toward war, a design that counterintuitively encourages leaders to launch wars. Political systems so designed are irrational and urgently need reform.
The fog of war that clouds the state of the battle is nothing compared to the fog of causality that makes nearly impossible the distinction between a war launched for national security and a war launched for the personal profit of the leader who gave the order to attack. By the time a leader works up the nerve to risk all on war, even he likely cannot make the distinction. Recent wars are swamped with evidence that politicians and leaders of the broader military-industrial complex gained such massive personal profit from the wars that it begs credulity to imagine that the visions of that personal profit did not color their decision to support the decision to launch the war.
Illogically, the political system is designed to encourage war for personal gain. Leaders, during war, are almost guaranteed support, and later few will want to uncover old dirt by looking into the motivations of those who "defended" the nation, for even the most egregious aggression is always called "defense." Voters, sick with war fever, can seldom differentiate between supporting the war leader and being patriotic, even though the two positions have no necessary relationship whatsoever. Making the argument that "harming the war effort" would be the patriotic course if the war were being fought for the benefit only of some corrupt political faction seems logical enough in an academic setting but gets nowhere in an angry crowd. Saying you love your country so much you want to make it admit that the ultimate decision (to start a war) was not correct and should be reversed is simply too much for most humans to contemplate (call that arrogance, cutting off your nose to spite your face, or--if you want to be polite about it--cognitive dissonance).
Leaders tend to benefit personally by committing the worst sin any leader can commit - launching an unnecessary war, but the argument over whether the leader's motivation for starting a war was primarily to win reelection/line his pockets or primarily to protect society will never be decided in time to matter if it ever be decided at all. Therefore, logically, the political system should be designed to protect society from the disaster of an unnecessary war.
For the U.S., a "war amendment" to the Constitution might be considered, with provisions designed, first, to clarify what legally constitutes a "state of war" (something that has become utterly meaningless with the advent of mercenaries beyond the reach of Congress and drones) and, second, to implement reforms that would impose personal costs on any leader launching a war, with those costs not so onerous that a patriotic leader would not accept them as the price of doing his duty but sufficiently onerous so as to persuade most leaders not to start wars for career advancement.
To clarify the "state of war," the following might be useful:
- No military forces may be maintained under the direct command of the President without the oversight of Congress;
- When forces representing the U.S. employ force overseas, whether uniformed or mercenary, "war" exists;
- "War" is illegal without the express permission of Congress, with the automatic penalty that the President be immediately removed from power.
- Within 24 hours of launching a war, the President and Vice President shall both resign, with no right to hold elective office for five years and no right to work ever in their lifetimes for any firm that produces weapons or holds government contracts related to the war effort or engages in the financing of the war effort;
- Members of Congress who vote for war shall be ineligible for reelection when their term ends and similarly prohibited from working for the military-industrial complex;
- Presidents cannot be reelected without leaving power for one term;
- Members of Congress can only be reelected twice;
- CEOs of corporations that sell weapons or provide contractors and supplies for the war effort shall have their salaries cut to minimum wage levels for the duration of the war.
Finally, the electoral system must be reformed to prevent buying elections. The easiest step in this direction is to provide free TV time for campaigns. The real free speech issue in modern society is not the corrupt idea that dollars equal votes but the defense of the "communications commons:" TV stations should be required, as a condition of using the common airwaves, to offer free time to all candidates and prevented from offering any paid time. However society decides to allocate time to candidates on TV, money should have nothing to do with it.
