I have not seen his comments in the Arabic media and whatever a junior minister says on Twitter during a tense time for the region should not be taken for more than it is. I don't think that the cordial relations between UAE and Pakistan will be damaged at all nor is the UAE going to deport Pakistanis.
I frankly, as I wrote earlier, am happy with Pakistan's decision although it was always about a symbolic gesture. 1000 mountain troops would be good though due to the experience and just to give the coalition further legitimacy.
Without comparing anyone with the US then they too did never invade Afghanistan or Iraq on their own. They had a coalition of dozen upon dozen of countries to rely on as well. Most of it was politics as well.
Trust me the Arab leaders have realized that they need to deal with their own problems and conflicts hence the Arab joint force of 40.000 soldiers no matter how big our house is and how difficult it is to keep it clean and how many "guests" we meet in the process if you understand what I am alluding to here.
