Quote: It also shows that if you make a deal with the US that the US is not trustworthy. Iran has not violated the agreement.
I'm going to put forth the suggestion that you're not really disturbed by the fact that Trump is breaking a deal. What bothers you is simply a politician won the presidential election who you did not vote for.
When Obama broke the agreement with Poland and the Czech Republic for the missile defense technology Bush had negotiated, you had no outrage. There is no post from you declaring that Obama is showing the world that the US is not trustworthy. From one Czech lawmaker, "If the Administration approaches us in the future with any request, I would be strongly against it." No post from you about the US going against its allies.
Gaddafi gave up his WMD arsenal during the Bush administration, and agreed to let weapons inspectors into Libya to help dismantle its chemical and nuclear weapons programs. This was done with the understanding that those countries sending inspectors wouldn't then invade Libya and force him out of power once he disarmed. When the Obama administration did exactly that, where was your frustration? I've seen nothing from you exclaiming that such actions by the US discourage North Korea from halting its nuclear weapons program.
You didn't express concern then about one president reversing course on a deal with foreign governments negotiated by the previous president. From late January 2009 through January 2017, it was fine whenever that happened. But on January 20th, 2017, backing out of a deal negotiated by the previous administration all of a sudden shows the US is untrustworthy. Strange how that timing works.
Very similar behaviors by Obama and Trump. But you had no great desire to run to the keyboard and alert the world that the US president took action which shows the US is untrustworthy until the behavior was from Trump.
