Considering that the Second Intifada was sparked by former Israeli PM Ariel Sharon's storming of Al Aqsa Mosque in 2000, Ben-Gvir's recent stunt is clearly a dangerous provocation. Israeli politicians like Netanyahu and Ben-Gvir are far-right religious nationalists who believe that all of Palestine should be annexed and occupied by Israel. Theatrics like this could seriously worsen an already violent situation; in the last year, Israeli forces have killed over 200 Palestinians, and Ben-Gvir's visit signals that such violence will continue.
The controversy regarding Ben-Gvir's visit is just another example of the double standard to which Israel is held. When Jews want to visit the Temple Mount, which they consider the holiest site in their religion, they're severely criticized by world governments and the media. However, when Palestinians incite violence and riots because they can't accept Jews' rights to pray at their holy site, they're applauded. Either way, Ben-Gvir's visit doesn't threaten the status quo or previous agreements.
