Peter Bergen wrote for CNN about Trump's options in Syria:
Asked what would shape the future of his government, British Prime Minister Harold Macmillan is said to have remarked "Events, dear boy, events."
The Trump administration just had its first big international event: Syrian dictator Bashar al-Assad's regime appears to have carried out a chemical attack against its own people, killing dozens, including many women and children.
The video images of young children writhing in agony and being hosed down with water are indelible. And those images certainly now have the attention of President Donald Trump, who said on Wednesday, "I will tell you, what happened yesterday is unacceptable to me ... It's already happened that my attitude toward Syria and Assad has changed very much."
