Hezbollah has constructed quite the elaborate justification for slaughtering Sunni Arabs in Syria for Boy Assad:
Hezbollah's rapidly expanding role in Syria is regarded as part of a strategic decision undertaken by the party, Damascus, and Tehran to safeguard the Assad regime at all costs. To soothe any misgivings among Hezbollah's rank and file, the party's leadership has crafted a narrative that the West and Israel are using militant Sunni jihadists to oust the Assad regime and weaken the "resistance front" of Iran, Syria, and Hezbollah for the benefit of the Jewish state.
It is a rationale that has been absorbed by the Hezbollah combatants. Asked how he felt to be fighting Arab Muslims today, having not fought Israeli troops for nearly seven years, Abu Khalil shook his head.
"No, we are fighting Israelis in Syria," he says. "Only they are wearing a dishdash and carrying the Quran. But it is the same Western and Israeli project that wants to weaken the resistance."
There's a lot of room for dead Moslem Arabs with that thinking that defines Moslem Arabs as just Jews in disguise.
Like in the Iran-Iraq War. Iran justified their furious assaults on Iraq as a means to get at the Israelis. The Iranians killed at least 200,000 Iraqis at the cost of at least 400,000 Iranians during that war under that rationale.
[UPDATE: From this post: "Iran justified continuing the war with offensives against Iraq as Iran's attempt to go through Iraq to get at the real enemy--Israel. When Saddam said that Iran was diverting the Moslem world from dealing with Israel (then fighting in Lebanon) the Ayatollah Khomeini denied that, saying ""We shall get to Lebanon, and to Jerusalem, through Iraq." (from an old unpublished manuscript of mine on the Iran-Iraq War)"]
You have to hand it to the Hezbollah terrorists for being a dedicated lot. After all, they're willing to fight the Jews despite Israel's apparent ability to convince Sunni Arabs to fight Assad.
But Hezbollah knows they can teach their twisted speech to the young believers. They're working hard in Qusair. Working for the clampdown.
