A short WINEP commentary on Hezbollah's role in the Syrian civil war:http://www.washingtoninstitute.org/p...losing-the-war

Amidst the conclusion:
To be sure, fighting in Syria has hardened a new generation of Hezbollah militiamen, but it has also depleted the group's ranks and eroded its carefully cultivated image as an organization devoted to "resisting" Israel
A wider commentary in Strife, a Kings War Studies blog, reviews the stalemate between Hezbollah and Israel. The author concludes:
Finally, the events in January 2015 can be considered the latest reminder of a strategic stalemate along the border. The law of talion, ‘an eye for a tooth’[9], which represented the Israeli strategy during the hostilities in 2006, set the pattern for the conflict. Israel and Hezbollah now tacitly adhere to an even-tempered rationale. In the foreseeable future it will be ###-for-tat, rather than all-out war, that will characterise the ever volatile tri-border area.
