Biden plays it safe in the State of the Union speech. The president of the United States faces his most important intervention of the year this Thursday amid doubts about his ability to be re-elected.

The challenge is great, above all, for a man who was never particularly comfortable in the arts of oratory. It is not clear whether during that long speech he will quote his opponent, Donald Trump, although it can be taken for granted that he will talk about Ukraine, Israel's war in Gaza, China.
