President Trump's overall approval rating has edged slightly upward following his airstrike against Syria last week, even as most respondents were unsure about escalating U.S. involvement. While 57 percent of Americans in a CBS News poll approved of the initial strike, just 18 percent want ground troops in the country and seven-in-10 believe Congress would need to authorize any further action.
Other polls similarly show Americans' uncertainty about involvement in Syria.
Since the strike, 43 percent of Americans approve of Trump, whereas in a similar CBS News poll conducted in late March, Trump was approved of by just 40 percent of the country.
The poll was conducted April 7-9, sampling 1,006 adults in English and Spanish. The margin of error is plus or minus four percentage points.
