The ten Senate Foreign Relations Committee members who voted to attack Syria received 83 percent more campaign contributions from defense contractors than the seven senators who voted against it, according to analysis from Maplight.org.
Examining data from 2007 to 2012, the analysts found that the average senator who voted “yes” on the authorization of the use of military force took $72,850 from defense contractors and other defense industry interests. Senators who voted “no” received just $39,770 on average.
Arizona Republican Sen. John McCain led the pack among those in favor, raking in about $176,000 from defense interests over five years. Illinois Democratic Sen. Dick Durbin garnered $127,000 from the defense industry, followed by Virginia Democratic Sen. Tim Kaine, who picked up a cool $101,000.
Defense lobbyist are another red herring just like the "pipeline" or 1400 dead syrians when hundreds of thousands have been killed, or enforcing international law norms by violating international law norms, etc.
This is about Israel and Iran. The primary issue in the ME in the cause for an unwanted, unnecessary and destructive war.
Getting an average of $70k over several years , from the defense industry ,hardly seems like serious motivation to go to war. I'd imagine the defense industry favors them because they are more hawkish & supportive of the defense industry general anyway
