Letter Published in The National UAE on 5Nov 17, The US should tighten security measures at home      In reference to your story Trump threatens to end green card lottery after fatal truck attack(November 2), the United States has witnessed many terror attacks in recent months. Given that the country has taken the fight against terrorism to a global level, it should be ready for such attacks and tighten security measures at home. Furthermore, the attacker said he did this in the name of ISIL but claims of co-ordination with group masterminds must be verified and substantiated, as this tyrannical group does not deserve any overstatement of their power to wreak destruction.K Ragavan, India
