ARETHUSA,
barack the way he intends it, is most probably the arabic form of the word
baruch(CH as in BACH) which is a common hebrew name too.
the same letter with a dot becomes C. like BARAC, arabic may use that word.
Just as hebrew says Shlomo, the arabic form is Sulaiman, (the difference in hebrew, and probably arabic too, between SH and S, is just a dot)
barack is arabic for bless/blessing..
Obama is probably a common name.
separating it to O BAMA and asking what that is in hebrew.. well, that's like taking BARACK, separating that to B ARACK and saying that because B means IN, and ARACK is a kind of alcohol, we have discovered that his name means In Arack(arak is a kind of alcohol). i.e. he promises blessing but really he will turn people to drink.
don't pay too much attention to ridiculous articles based on wordplay, and know that a person that calls himself "Rabbi", and believes in Jesus , is not a Rabbi. (your post

Barack may well bode badly for the future, but we don't need to turn to ridiculous theories to make the case..
People have always thought that -now- the end is nigh, and come up with crazy theories that break when thei characters fade away.
note- barack spelt with a kuf means lightning(strongs 3000 as your article said
http://www.blueletterbible.org/lang/lexicon/lexicon.cfm?strongs=H1300 ). However, I would bet he spells it with the arabic form of kaf. Blessing.
