It's our violent culture. Every house in Switzerland has a gun. Every house in Israel has a gun. Almost no gun crime in either place.
This line is often used by anti-gun control advocates. However it's really apples and oranges:
From the Times of Israel: "Israelis must meet a detailed list of criteria to be allowed to own a firearm. They must ask the state for a license, are permitted only one gun at a time, and must even ask for permission to sell their gun. And the Firearms Licensing Department is no rubber stamp: Roughly 40 percent of requests are rejected.
Indeed, before even requesting a license, Israelis must meet minimum age requirements, be in good health and of sound mind, and have no criminal record, among other preconditions.
There’s more. Once they are granted the right to carry a gun, Israelis are limited to just 50 bullets in their possession at any given time. They must shoot or return old bullets before they can buy new ones, a process that can only take place at tightly regulated shooting ranges where each bullet’s sale is carefully registered. The types of guns permitted also depend on the reason for the license."
Switzerland, from Wikipedia:
In order to purchase most weapons, the purchaser must obtain a weapon acquisition permit (art. 8 WG/LArm). Swiss citizens and foreigners with a C permit over the age of 18 who are not under a curator nor identified as being a danger for themselves or others, and who don't have a criminal record with a conviction for a violent crime or of several convictions as long as they haven't been written out can request such a permit. Foreigners with citizenship to the following countries are explicitly excluded from the right to possess weapons: Serbia, Bosnia and Herzegovina, Kosovo, Macedonia, Turkey, Sri Lanka, Algeria and Albania.[note 1] The following information must be provided to the cantonal weapon bureau together with the weapon application form:
valid official identification or passport copy.
criminal record copy not older than 3 months.
For each transfer of a weapon or an essential weapon component without weapons acquisition permit (art. 10 WG/LArm), a written contract must be concluded. Each Party shall keep them at least ten years. The contract must include the following information (art. 11 WG/LArm):
Family name, first name, birth date, residence address and signature of the person who sells the weapon or essential weapon component.
Family name, first name, birth date, residence address and signature of the person who purchases the weapon or an essential weapon component.
Kind of weapon, manufacturer or producer, label, caliber, weapon number, and date and place of transfer.
Type and number of the official identification of the person who acquires the weapon or the essential weapon component.
This information must be sent within 30 days to the cantonal weapon registration bureau, where the weapon holders are registered (art. 9 WG/LArm).
Some weapons do not need a weapon acquisition permit (art. 10 WG/LArm):
Single-shot and multi-barreled hunting rifles and replicas of single-shot muzzle loaders.
Hand bolt-action rifles, which are commonly used in off-duty and sporting gunnery recognized by the military law of 3 February 1952 and shooting clubs for hunting purposes in Switzerland.
Single-shot rabbit slayer.
Compressed air and CO2 weapons that develop a muzzle energy of at least 7.5 joules, or their appearance may be mistaken for real firearms.
Ready ammunition of the Swiss Army. Soldiers equipped with the Sig 550 assault rifle used to be issued 50 rounds of ammunition in a sealed can, to be opened only upon alert and for use while en route to join their unit. This practice was stopped in 2007.
In order to purchase ammunition, the buyer must follow the same legal rules that apply when buying guns. The buyer must provide the following information to the seller (art. 15, 16 WG/LArm; art. 24 WV/OArm):
a passport or other valid official identification (the holder must be over 18 years of age) with valid address.
a copy of their criminal record not older than 3 months, or a weapons acquisition permit which isn't older than 2 years (art. 24 § 3 WV/OArm).
The seller must verify that the buyer is not psychiatrically disqualified nor identified as posing security problems (art. 8 § 2 WG/LArm).
Further, they must not be a citizen of the following countries (art. 12 WV/OArm): Serbia, Bosnia and Herzegovina, Kosovo, Macedonia, Turkey, Sri Lanka, Algeria and Albania).
A Swiss 100 gram black powder container.
The possession of the following ammunition is generally prohibited:
Ammunition with projectile containing an explosive or incendiary device.
Ammunition with one or more projectiles releasing substances which damage the health of people in the long run, particularly those mentioned in annex 2 of the WV/OArm.
Ammunition, missiles and missile launchers for military explosive.
Ammunition with projectiles for transmitting electric shocks.
Ammunition for handguns which may cause deformations."
In other words both countries have sensible control.
