We'll need to brainstorm how those characters can get involved in the plot, if you haven't done so already. You wouldn't want to miss out on the Dubai battle. Israel couldn't have a large scale there because they'd need to cross the heavily defended enemy territory, but they could drop in smaller amounts of help secretly. As for the guy, it will be harder coming up with why he'd be caught up in an active war zone. Unless he was captured while doing something else and brought over to Dubai for some reason.
