It's amazing how many countries Obama has made the same speech to. Every country is "one of America's strongest allies" and "punches above their weight".
I support Obama (in so much as I prefer him to any Republican nominee) but I find this highly embarassing for him. You would think that the president of the USA would have some of the finest speechwriters working for him but it seems like all they've done is use the "copy and replace" tool in Word every time Obama visits a new country.
Many media orgs. around the world have picked up on this story which will very likely damage Obama's global reputation.
Politicians are there to say what needs to be said: they are not writers and thus expected to produce work different than that done previously. This has been going on for most of modern international diplomacy and is nothing new - statesmen usually prefer to keep it safe and unoriginal rather than risk with originality.
In any case it is hardly a case of "copy and paste" all the time as most are isolated incidents.
