Lets be honest my friend there have been numerous incidents starting from Afghanistan occupation of USSR that the US supported mujahideens in the name of religion to unite in and fight the non believers in russiaThey got brainwashed in the name of religion under a policy of USThis event created the Taliban and Alqeda supported by USIt stuck them in their back is a different storyThe dismantled army of Iraq supported by Israel and US as a policy to smuggle oil created ISISRussia returned the Afghanistan favour hereThe syrian kids killed and the ones orphaned in war will again be brainwashed in the name of religion to fightback and take revengeThe problem is the US state policy for selfish motives If Trump wishes to change this parasitic US policy then there is a possibility of limiting this threatHowever if he still wishes to solve problem by force and confrontation used earlier the problem will aggravate furtherYou cant scare the person ready to die with fear of death
