"We don't have any other options, with the Americans or without the Americans", Assad told RT in an interview.
He added: "The Americans should leave, somehow they're going to leave".
For Israel, the goal is to stop Iran's penetration of Syria and weapons transfers to Hezbollah. Prior to this, many times had Israel shown concern about Iran's expansion techniques using the seven-year conflict.
In an interview with Russia Today, Russia's state-owned global broadcaster, Assad said the United States should heed the lessons of Iraq and get out of Syria before they are forced to leave.
On April 14, the US, Britain and France launched a coordinated missile attack against sites and research facilities near Damascus and Homs with the purported goal of paralyzing the Syrian government's capability to produce chemicals.
In an interview with Russia Today, Mr Assad said he did not have a nickname or insult for Mr Trump: "This is not my language, so, I can not use similar language". "The only option is to improve our air defense, this is the only thing we can do, and we are doing that".

The three countries, the EU-3, have been working to keep Iran in the nuclear deal with the West, also called the Joint Comprehensive Plan of Action (JCPOA), following the United States' withdrawal from the deal two weeks ago.
Israel has warned it will not tolerate a permanent Iranian military presence in Syria. The official, who spoke on condition of anonymity because he was not authorized to speak to the media, gave no further details.
Moreover, there was much to be gained by avoiding the appearance of the Russians doing nothing in the face of its main competitor, the US, operating so close to its forces and demolishing its ally.
But in February, U.S. -led coalition airstrikes killed several Russian private contractors that appeared to be advancing with pro-government forces on a position held by Syrian Kurdish forces in Deir el-Zour.
Israel has been pledging for months to prevent its main enemy Iran from entrenching itself militarily in Syria, where Tehran is backing President Bashar al-Assad's regime.
President Trump has said that he is keen to pull the troops out as soon as possible, but the US military has persuaded him to allow them to remain at least until a last pocket of Islamic State fighters is vanquished along the Syrian-Iraqi border.
