Trump Teases Syria Attack: I Never Said When It Would Happen

President Donald Trump tweeted again Thursday about a potential attack on Syria in response to the suspected chemical assault that took place last weekend in the country, but now he suggested retaliation could come at any time.

In a tweet that social media users criticized for failing to grasp the gravity of the situation, the president appeared to tease the possibility of a strike against Syria, while perhaps backpedaling on its imminence. He also questioned why his administration hadn't received more gratitude for dealing with the Islamic State militant group (ISIS).

"Never said when an attack on Syria would take place. Could be very soon or not so soon at all!" he tweeted. "In any event, the United States, under my Administration, has done a great job of ridding the region of ISIS. Where is our 'Thank you America?'" he added.

The suspected attack in Syria, which took place in the city of Douma on Saturday, left at least 40 people dead and around 500 others injured, according to the Syrian American Medical Society. However, the exact number of people affected by the attack is unknown, with conflicting figures emerging from local reports.

Following the alleged attack, an aide to Trump said Sunday that no response was "off the table" when it came to responding to the suspected incident. The president himself sent a series of tweets on the topic, with one Wednesday message suggesting that he was likely to pursue military action.

"Russia vows to shoot down any and all missiles fired at Syria," Trump tweeted. "Get ready Russia, because they will be coming, nice and new and 'smart!' You shouldn't be partners with a Gas Killing Animal who kills his people and enjoys it!" he added.

The president's Wednesday tweet came after Russia warned the U.S. against striking Syria, as it did following the Assad regime's deadly Khan Sheikhoun chemical attack in 2017.

Despite Trump responding with gusto to Russia's warning, he appeared on Thursday to be drawing his cards closer to his chest with the tweet about the timing of a potential attack.
