I do not think that building of The Temple will create any global furore. Everywhere the situation may remain under control. Only at POK, the payjamah cladded bearded agents of Pap666 may stage some demonstration waving BS green flags with hammered sickled moon and weeping star. A molana shall be addressing them in broken words muttering somethings like jihad, fatwa, mishrikh, kuffra, Zionism, Kristan, Hindu etc. But the sign will be that he will be drinking a full glass of water before completion of each of his sentences.
This should be the most suitable period for Temple building, so that Iranians may tend to commit some forced errors.
