I agree! The others are nice, but [name]Zane[/name] is completely perfect for a name that crosses over really well in both cultures. 
[name]Love[/name] [name]Zane[/name]!
I glad you said it [name]Pam[/name]. That is what I thought of too. I am sure you want your son to start life as his own person.
A Lebanese/Australian family I know have a [name]Gus[/name] and [name]Ali[/name]. [name]Both[/name] adorable!!
I know a few Kareems but I’m from a city with a big Muslim population and a big black population and there’s a crossover there. It doesn’t sound “ethnic anonymous” though, not trying to be rude. I would be surprised to meet a white [name]Christian[/name] [name]Kareem[/name].
I like it well enough, but if you’re willing to step out of bland as much as that, I like [name]Malik[/name] and [name]Tariq[/name] more. They’re also not “anonymous” though, I won’t say they are, I just like them.
[name]Zane[/name],
definitely!
I love [name]Kareem[/name] and Kais!
I agree about [name]Zane[/name]. From your new list, I would also say [name]Nadeem[/name] and [name]Kareem[/name] would be easy. I went to college with people with all three of those names. (All from Connecticut, not international students.) I would imagine most Americans would associate [name]Kareem[/name] with [name]Kareem[/name] [name]Abdul[/name]-[name]Jabbar[/name], the basketball player.
Thank you so much for your incredible input, it appears that [name]Zane[/name]/Zayn is by far the winner, which makes my life a little easier 
I am very happy! As an American who lived in [name]England[/name] and who has a child who grew up to live in [name]France[/name] – not to mention a name author! – I am sensitive to how difficult it can be to tease out the cross-cultural nuances of names. You are a great parent to be thinking about this topic now!
Looks like I got to the party a bit late. [name]Zane[/name]/Zayn is a solid choice. Could I just mention that [name]Laith[/name] would be a great name for [name]Zane[/name]'s little brother?
I really like [name]Raffi[/name], [name]Laith[/name] and [name]Zane[/name]. [name]One[/name] of my own fav is [name]Omar[/name]! Would love to use that one, but it doesn’t make much sense for me…
Good luck!
My name is Nihad (nee-had) so even closer to Jihad and this was not an issue. For the record I have only lived in major cities NYC (and even lived there during 9/11), San [name]Francisco[/name] and that may make a difference. I do get people often asking the meaning which I believe is “great heights”. I think avoiding Ziad because of this association plays into cultural ignorance and isn’t a good enough reason.
However, I do think it’s important to think about the setting and culture surrounding the child and here is why:
I’m half palestinian /half italian american from NJ so my italian family hated it, my arab family loved it. My sisters name is [name]Nicole[/name], so that made an odd sibset, and I also do not look very middle eastern so when people meet me they are often thrown for two reasons. [name]One[/name]- they think its a male name (Nihad is unisex in arab culture) and two- they expect someone who looks more arab than I do ( in college people didn’t realize I was the Nihad on the floor, they were waiting for the “foreign girl” to show up) . I love my name because it is a great feeling when people remember mean over others or don’t even need to know my last name because I’m the only Nihad in the company. I’ve got a one name persona, much like [name]Madonna[/name] or [name]Prince[/name]. Most people don’t even remember my last name yet I find people always remember me years later. However, I do wish my parents had put a little more thought into making it more feminine or making more sense within our individual family /sibset.
Sorry this is a bit of a ramble that doesn’t have a ton to do with the original question but I was a little put off by the idea of avoiding a name because people who don’t know better would have their feathers ruffled.
All that being said, I do like [name]Zade[/name] or [name]Zain[/name] better than Ziad. [name]Zane[/name] to me is pretty feminine. I do know a lot of female [name]Zain[/name]'s.
