One thing is clear, though: it must hurt the Netanyahu Regime financially and/or militarily so much that it changes its stance. At the same time, it must not hurt Israel's defensive capacity (over 9,500 inbound missiles from just Hezbollah within a year is a clear threat that must be countered).
For instance, but...
