On April 7, 2017, Trump ordered the United States Navy to launch cruise missiles at Shayrat Air Base in response to the Khan Shaykhun chemical attack. The response had wide international support and was highly praised by the majority of Republicans as well as Democratic senators, and many countries, however it drew criticism from Russia, who the United States had warned in advance about the attack. Although Russian anti-missile defenses such as S-300's failed to deter the missile attack, Russian forces suffered minimal damage, as the United States had intended to avoid striking areas of the base used by Russia. Russian Prime Minister Dmitry Medvedev called the strike "good news for terrorists".
