Those are American dollars at work. Pains me to see that.
In early 2001, ground was broken for the construction of several additional churches on a parcel of land in Jebel Ali donated by the government of Dubai to four Protestant congregations and a Roman Catholic congregation. Construction on the first Greek Orthodox Church in Dubai (to be called St. Mary's) began at the end of 2005. The land for the construction of the church was also donated by the government to the Greek Orthodox community of Dubai.
Financial support to non-Muslim groups from the Dubai government comes in the form of donated land for the construction of churches and other religious facilities, including cemeteries. They are permitted to raise money from among their congregants and to receive financial support from abroad. Christian churches are permitted to openly advertise church functions
You may be right (I'm not sure) about the level of anti-semitism present in Dubai. Putting that aside for a moment, it is truly awesome what Dubai is doing in terms of their economy. Look at every other pathetic arab nation wasting their oil. The pictures you present are an incredible testiment to what is possible when hate is pushed aside. I congratulate them for what they are doing.
Even today, only 10% of their revenue comes from oil. And I'd say they have a general commerce strategy that includes all sorts of businesses, rather than just tourism.
