Border crossings closed, Hungarian highway empty

Looks so peaceful without the hordes of migrants. Why won't Serbia protect its borders? Foreigners do not have a right to march through another's country with the required legal papers, and in such numbers to overwhelm the host country.
They don't have the right to litter and trash the buses, trains, roadways, farmer's fields, orchards, etc., but they are leaving a huge amount of trash in their wake. Videos show them wasting food and water in Hungary: taking large new unopened bottles of water and kicking them onto the train tracks.
