The Letter from the 47 Traitors was a shot across the bow of Iran. However, it wasn't a warning but, a promise that as soon as they can the Republican Party will declare War on the Iranian People. Well, to be clear, the Republicans plan to send other Americans' children to war.
The Right-Wing Warmongers feel they have the perfect poster boy in Senator Tom Cotton, who despite being so stupid that he doesn't know that Tehran is the Capital of Iran, is leading the charge.
Tehran Tom is a true believer. He still believes the George W(orst POTUS Ever) Bush Administration Big Lie that Saddam was involved in 9/11, that Iraq still has WMDs, and the Iraq debacle was a Great and Noble Crusade. Senator Cotton is now calling for a ramp-up of Military spending to match the 1980's because he is a full-fledged member of the Military-Industrial-Congressional-Complex.
So, of course, Tehran Tom was chosen by Bloody Bill Kristol and the D.C. NeoCons to lead the Iran War Propaganda Charge. War with Iran will accomplish a great deal for the Republicans.
First, of the high-ranking Republicans leading this Crusade, all but perhaps one or two will have no family members anywhere near the War. The Young Republicans on college campuses will again beat the War Drum from the safety of their Quads. It'll just be working class Americans suffering and Republicans love when Poor people suffer.
Second, the Republican Party is a wholly owned subsidiary of the Rich. The Rich used the Iraq War to steal at least 3 Trillion Dollars from the American People. A New War in Iran will be a windfall for the Rich while also providing the a crushing debt which the Rich will use to steal Social Security.
You see the Bush's Iraq War and the Huge Deficits associated with it have been used by Conservatives for over a decade to slash spending for the Social Safety Net and hamstring President Obama.
So, not only do the Rich get Richer, the Poor get Poorer. And when the Republicans launch the War on Iran a New Generation of Veterans will come home damaged and broken to be spit upon and left to suffer and die by the Republican Party.
