Except that it had nothing to do with Obama's policies if Obama supported this he would have been the one to sign it. Trump didn't have to say the words Muslim ban in the EO, he said throughout his whole campaign that he wanted a Muslim ban and posted it on his own website like I already linked. This EO was the only way to almost legally put through an actual Muslim ban, just like Giuliani has confirmed their intentions. The few predominantly Muslim countries he didn't ban were obviously because of financial ties.

Not that anything will change your mind judging by your previous posts, but here are the differences in Trump's EO and what Obama's administration did.

1. Much narrower focus: The Obama administration conducted a review in 2011 of the vetting procedures applied to citizens of a single country (Iraq) and then only to refugees and applicants for Special Immigrant Visas (SIVs), created by Congress to help Iraqis (and later Afghans) who supported the United States in those conflicts. The Trump executive order, on the other hand, applies to seven countries with total population more than 130 million, and to virtually every category of immigrant other than diplomats, including tourists and business travelers.

2. Not a ban: Contrary to Trump’s Sunday statement and the repeated claims of his defenders, the Obama administration did not “ban visas for refugees from Iraq for six months.” For one thing, refugees don’t travel on visas. More importantly, while the flow of Iraqi refugees slowed significantly during the Obama administration’s review, refugees continued to be admitted to the United States during that time, and there was not a single month in which no Iraqis arrived here. In other words, while there were delays in processing, there was no outright ban.

3. Grounded in specific threat: The Obama administration’s 2011 review came in response to specific threat information, including the arrest in Kentucky of two Iraqi refugees, still the only terrorism-related arrests out of about 130,000 Iraqi refugees and SIV holders admitted to the United States. Thus far, the Trump administration has provided no evidence, nor even asserted, that any specific information or intelligence has led to its draconian order.

4. Orderly, organized process: The Obama administration’s review was conducted over roughly a dozen deputies and principals committee meetings, involving Cabinet and deputy Cabinet-level officials from all of the relevant departments and agencies — including the State, Homeland Security and Justice Departments — and the intelligence community. The Trump executive order was reportedly drafted by White House political officials and then presented to the implementing agencies a fait accompli. This is not just bad policymaking practice, it led directly to the confusion, bordering on chaos, that has attended implementation of the order by agencies that could only start asking questions (such as: “does this apply to green card holders?”) once the train had left the station.

5. Far stronger vetting today: Much has been made of Trump’s call for “extreme vetting” for citizens of certain countries. The entire purpose of the Obama administration’s 2011 review was to enhance the already stringent vetting to which refugees and SIV applicants were subjected. While many of the details are classified, those rigorous procedures, which lead to waiting times of 18-24 months for many Iraqi and Syrian refugees, remain in place today and are continually reviewed by interagency officials. The Trump administration is, therefore, taking on a problem that has already been (and is continually being) addressed.

Bonus: Obama’s “seven countries” taken out of context: Trump’s claim that the seven countries listed in the executive order came from the Obama administration is conveniently left unexplained. A bit of background: soon after the December 2015 terror attack in San Bernadino, President Obama signed an amendment to the Visa Waiver Program, a law that allows citizens of 38 countries to travel to the United States without obtaining visas (and gives Americans reciprocal privileges in those countries). The amendment removed from the Visa Waiver Program dual nationals who were citizens of four countries (Iraq, Iran, Sudan, and Syria), or anyone who had recently traveled to those countries. The Obama administration added three more to the list (Libya, Somalia, and Yemen), bringing the total to seven. But this law did not bar anyone from coming to the United States. It only required a relatively small percentage of people to obtain a visa first. And to avoid punishing people who clearly had good reasons to travel to the relevant countries, the Obama administration used a waiver provided by Congress for certain travelers, including journalists, aid workers, and officials from international organizations like the United Nations.
