Why Israel needs to finish the job now:

Iron Dome can defend successfully against a handful of rockets fired simultaneously in the general direction of Israeli cities. At some point Israel’s enemies will acquire the capability to fire large salvos of precision-guided weapons at key military or civilian targets and overwhelm the existing defenses. GPS-guided rockets are not that difficult to make. Iron Dome gives Israel a respite, not relief in the long term.

Israel has an extraordinary opportunity that may not last. It can protect its citizens from retaliation for the time being. Its right to self-defense is so obvious that Western governments usually hostile to Israeli interests must affirm its right to self-defense. Even the German Left Party (“die Linke”) is split, with some of its leaders attending pro-Israel rallies while others join the largely Muslim demonstrators chanting “Jude, Jude, feiges Schwein, Komm heraus und kaempf allein” (“Jew, Jew, cowardly pig, come out and fight alone”). It has the tacit (and sometimes not entirely tacit) support of Egypt, not to mention the Gulf states, in its war against Hamas. But it cannot afford a repeat of 2012, after which Hamas rebuilt its weapons capability. Where Hezbollah is concerned, the Chinese proverb applies: Kill the chicken while the monkey watches. The reduction of Hamas has to serve as a deterrent for Hezbollah and Syria, not to mention Iran.

Yes.
