Why Sudan doesnt attack UAE directly?

UAE is behind the Sudan genocide, they fund the terrorist rsf militia, wouldnt best way to stop this to go after the source? Does Sudanese military have any medium or long range missiles to attack the Emirates with? They can at least hit Dubai's financial center. Maybe the US, Israel, Iran or the Houthis can hook them up? What do you think? If rsf cannot be resupplied by air in chad from uae planes, they will collapse. thoughts about this?
