This term is so overused.
It's a flowery, distractive way to say "terrorist demands", without useing the term 'terrorist' or 'demand'. The 2 are indistinguishable.
The next time you hear an Osama-loving-sycophant-Arafat-apologist pundint using the term "arab street", swap it with "terrorist demands" and you'll find that they are one in the same.
'Arab street' = 'Terrorist Demands'
