Today Barack Obama is going to receive his first full secret briefing from US intelligence agencies on the threats his administration faces, as ABC News notes here. Many have said that within days of these briefings, past Presidents seem to have aged quite a few years.
President Obama is going to painfully discover that no matter even when the US has been right,just,fair and generous, there still exist a myriad of vicious enemies of freedom trying to destroy the USA.
The reaction from Iran today to his TV offer of "extending a hand" was calumny, bile, anger and insolent demands the US "apologise" for "past crimes", just one component of the hatred some regimes perpetually have for the USA - which Obama will find all his sweet words and charisma cannot change.
Obama will wake up to the painful realization that the USA cannot just be "liked", it also needs to be respected and fear of power is one ( vital) component of respect that he has never acknowledged.
Speak softly and carry a big stick, Barry as a former US President once said. You are going need it sooner rather than later.
After this briefing, Obama will change a lot of his mind about George W Bush, if he acknowledges it or not.
