The Islamic State of Iraq and the Levant (ISIL) may be forced to retreat from Iraq-Syria under relentless pressure from forces allied with Western powers, but the retreat is going to be painfully slow and despite retreat, ISIL will be far from being finally defeated. If ousted from west Asia, ISIL is likely to relocate in Africa and the Af-Pak and launch new offensives. It is already gradually moving to the south Asian region, which has the largest congregation of Sunni Muslims, who support the ISIL ideology. South Asia will also provide ISIL greater safety from Western forces and open opportunities to spread its tentacles in various countries of the south and central Asian region. If it eventually moves to south Asia in force, India will face a new, dangerous challenge from Islamic forces.
