It can mean the opposite of funny.
Or it can mean significant.
In his March 28 column in The New York Times, Roger Cohen wrote: “Trump’s United States of America has become an unserious country, the offender of the free world.”
He meant insignificant.
He concluded: “It is the hour to stand up for the European Union. Its democratic shortfall, weak external borders and shared currency mistakes have contributed to a political backlash. Less appreciated are the peace and stability it has provided to hundreds of millions of people over generations and the myriad ways – from disappearing cellphone roaming charges to cheap borderless travel – it has improved life for Europeans whose forebears lived in a charnel house. No miracle ever marketed itself so miserably.
“Merkel is the personification of the Union’s values; she was just bolstered by a local election victory. Russians have taken to the streets to protest against Putin’s corrupt regime and been brutalized. This is not over. Truculent Trump has abdicated responsibility. Europe must step into the void.”
What could be more serious?
