Lieutenant Commander of the Islamic Revolution Guards Corps(IRGC) Brigadier General Hossein Salami warned the Saudi rulers that continued war against Yemen will cost them dearly." If Saudi Arabia continues war in Yemen, it will gain nothing in there but a war of attrition and a strike at the foundations of their government, " Salami said, according to Fars News Agency. He also warned Riyadh against becoming more involved in the war against Syria, and said, " If they want to intervene in Syria militarily, they will not know the prospects of the post - intervention era; they don’t have any option but going to the negotiating table, and when they go the(battle) field after leaving the negotiating table, they will not able to do anything. " Elsewhere, Salami referred to Riyadh ' s attempts to lower oil prices in a bid to hit a blow at Iran, but " they were damaged most. If they want to weaken us, they will be harmed much more and if they leave the scene, more space will be left for us. " In relevant remarks earlier this month, Salami underlined that Riyadh has failed to implement its plots in the regional states, specially Iraq, Syria and Yemen, warning that its support for terrorism will backfire. " Today, Saudi Arabia is increasing the potential for making its own borders insecure by hiring mercenaries(for terrorist attacks in the regional states) and it is a saddening end for Saudi Arabia which thinks that it can confront the Islamic Revolution in a proxy war, " Salami said, addressing a gathering of Basiji(Volunteer) forces in the Northeastern city of Mashhad.Recommended:Saudi ground troops invade northern Yemen He also referred to Saudi Arabia's attempts to decrease the crude price, and said Riyadh hit itself the worst blow by this plot which has led to reduction in the country's reserves. Salami pointed to Riyadh's military intervention in Yemen, and said, "Yemen is a quagmire for Saudi Arabia's soaking in an illogical war without even an iota of success." Also, in April, Iranian President Hassan Rouhani said that lack of balance in Saudi Arabia and the country's continued failure in implementing its plots is pushing the region into growing instability. "The destruction of infrastructures of a poor country (Yemen) and killing children, women and men has no other meaning but the fact that a country has lost its balance and no other interpretation can be envisaged for it," Rouhani told reporters before leaving Tehran for Indonesia to participate in a summit to commemorate the 60th anniversary of Asian-African Conference in Jakarta. He said Riyadh has failed to materialize its wishes in Iraq, Syria, Lebanon and North Africa, and is now trying to make up for these failures by bombing yet another country in the region.
