Tidy up the ship.
This whole thing is turning out to be a huge head fake of sorts, almost comical yet ingenious. Israel has not admitted to anything, while Iran is downplaying the reports and claiming little or no damage. They don't want to admit that Israel could so easily penetrate their airspace or be obligated to respond. There are even hints that they may be blaming the incident on internal opposition. Meanwhile, Israel succeeds in maintaining the coalition that helped them thwart the massive attack on April 14th, including US approval for future operations in Gaza and Lebanon.
Stay comfy.
