The key to understanding why the ruins of this ancient pearl of the desert have become a target rests in jewish ‘sacred’ texts:
“The day on which Tadmor is destroyed will be made a holiday” (Yeb. 16b-17a).
“Happy will he be who shall see the downfall of Tadmor” (Yer. Ta’an. iv. 8)
“The future destruction of Palmyra will be a day of rejoicing for Israel” (Yev. 17a)
Palmyra is the Tadmor of the Bible .... https://theuglytruth.wordpress.com
