This administration is making the same mistakes - but in living memory of the first, with a less noble prize, and with complete derision of Congress and Americans' intelligence.
Trump got reelected with slogans like "no new war" and in less than a year he started at least one (arguably I'd say two with the 12 days wars as Israel knew ut couldn't win this one without American bombers) also makes me think none if this is a "mistake", just a long term plan to keep power.
"Good" news! The War on Drugs and The War on Terror have been combined with the invention of the concept of "narcoterrorism"!
But most of those doing the condemning were also supportive of Pres. Obama (or at least refused to condemn his actions) back in 2011 when he attacked Libya, and in 2013 and 2014 when he attacked Syria -- all of this happening after we should have learned from what we were doing in Iraq and Afghanistan.
Those people who didn't protest against Pres. Obama's illegal actions have lost moral high ground to protest against Trump.
Obama deliberately went to Congress for authorization to strike the Syrian chemical program in 2013, and after it quailed from taking a vote, the strikes didn't happen.
The 2014 strikes were against ISIS, not Syrian government forces, and carried out under the existing AUMF authorization to combat Al Qaeda and its affiliates. One can argue whether ISIS qualified (even the administration at the time acknowledged it was a stretch and wanted a more clear-cut resolution from Congress), but it definitely was a major terrorist threat in the region and had been working with AQ in the past.
