It is also not accurate for Mr. Trump to claim full credit for the collapse of the Islamic State’s self-proclaimed caliphate in Syria and Iraq. A significant amount of territory has been recaptured and major battles have been won in the last year, but Mr. Trump has largely overseen a strategy started under President Barack Obama.

The $1.5 trillion tax cut signed by Mr. Trump in December is his first major legislative achievement in office. But he is wrong to characterize it — as he has done at least four times this year — as the largest in history (at least three are bigger) or the first since President Ronald Reagan’s 1981 tax cut (most presidents since Reagan have cut taxes).

The ‘Trump bump’ in the economy

Mr. Trump is likely to boast about a roaring American economy and healthy job growth, though his claims should be viewed in context.

He has, for example, boasted at least seven times in the past two weeks that the black unemployment rate, 6.8 percent in December, is the lowest ever recorded. While true, it is the culmination of a longer-term trend. It is also an open question how much credit a president, especially in his first year, can take for the economy.

The same can be said of Mr. Trump’s repeated claim that nearly 2.4 million jobs have been added since his election in November 2016. The number is accurate, but appears less groundbreaking with the appropriate context: More jobs were added in the 14 months before his election than in the 14 months since.
