Hezbollah is certainly holding back and have not launched a full-scale attack on Israel, this typical of the fighting method of Hezbollah, Hamas, Iran and other Arab Countries.
Hezbollah as you say knows if they launched a full-scale ballistic missile attack on Tel Aviv they would get destroyed, they want to engage in a hit and run type of war to damage Israel by a thousand cuts and play the public relations battle hoping to get the US to withdraw support from Israel and to get the world to join their side in stopping the might Israel from attacking poor defenseless Hezbollah, a major missile attack on Israel would throw that strategy out of the door.
After being beat up like this I like to think that Iran and Company are learning to operate more like adults.
Russia and China may be helping them to be more responsible in their responses to the provocations of Israel.
Of course, I still want Israel to win but some folks may misinterpret my analysis of this.
Trump the wheeler and dealer seems to me to be the man needed to solve this mess in a way that ends positively for Israel.
