Two quotes, both of which are applicable to the apologists that, today, comprise our political class:
"Tomorrow hopes we have learned something from yesterday."
John Wayne (1907-1979)
"Those who stand for nothing fall for anything."
Alexander Hamilton (1755-1804)
The first shows that, during the last few decades - but especially today - our politician's attention to matters important has not 'Wayned'.
The second answers the question why our politicians have become so enthused with the concept that is the European Union.
