Israel is a secular nation, as are all others. Micah 6:8 is dealing with personal interactions, not nation state issues.
If someone is shooting into ones home with a .22 that might only be somewhat dangerous yet if one has a .357 they are likely going to blast the attackers. If the terrorist Hamas doesn't want Israel to hit them, they shouldn't be hitting at Israel. Israel is waging war against a terrorist organization that runs Gaza.
If England were under small rocket attack it wouldn't take long before they took decisive military action; as they should.
The conflict involving Israel is very complex but Israel is doing nothing that England, America and every other major nation hasn't done in the past and would do again today under similar circumstances.
Outside interference on both sides of the conflict has continually made matters worse. Far better if all this had been allowed to be settled long ago. Thanks to interference on the part of supposed pro-Israel and pro-Palestinian nations, the problems have only grown worse. It would be best all around if the situation were to be dealt with decisively.
Israel can't work a true deal with Hamas or establish peace with Hamas when Hamas has in their charter and continues to declare openly that they reject the right of Israel to exist and their goal is to see Israel exterminated.
Even so, some sort of cease fire will eventually be agreed to which will only serve as a brief time out of simmering as Hamas plans their next attack.
Most of the Stand For Israel rallies in America are in the form of praying for the peace of Jerusalem.
