Henryk, there was a time to best act. And we didn't. Most of all, for a bunch of reasons pretty sad. A good chunk is poor leadership. George W Bush, out of his depth and into wars with Afghanistan and Iraq, Obama's failure to act with Syria and later with Putin's initiatives, Trump's four years of international buffoonery, and now Biden's mediocrity dressed as wisdom.
The example we should have been studying was H. W. Bush and his excellent containment of Saddam Hussein.
