About the "differently", I said in the beginning of my response that I wouldn't go into details. This was already a large answer, and taking into account that the question of "supporting Israel" was about Christians, I supposed that the details are more or less known.
The question for the Catholics still remain: since being born "like that" was out of Virgin Mary's control, why didn't God decide this to happen earlier in the history of Humanity.
I mean there are also other questions to be asked, but let's not diverge from our main theme here.
When it comes to nations, they are often an "obstacle" to Christianity.
We accept those parts of the ethnical traditions that do not oppose Christianity.
We are not obliged to support any nation unconditionally.
