The following is from Wikipedia so you'll have to filter out the lies it contains such as "State of Palestine".
Israel–North Korea relations
Israeli-North Korean relations (Korean: 이스라엘-조선민주주의인민공화국 관계) are very hostile,[1] and North Korea has never recognized the state of Israel, denouncing it as an "imperialist satellite".[2] Since 1988 it recognises the sovereignty of the State of Palestine over all of Israel, except for the Golan Heights, which it recognizes as part of Syria.
History
North Korea sent 20 pilots and 19 non-combat personnel to Egypt during Yom Kippur War. The unit had four to six encounters with the Israelis from August through the end of the war. According to Shlomo Aloni, the last aerial engagement on the Egyptian front, which took place on 6 December, saw Israeli F-4s engage North Korean-piloted MiG-21s. The Israelis shot down one MiG, and another was shot down by friendly fire from Egyptian air defenses.[3]
Over the years, North Korea has supplied missile technology to Israel's neighbours, including Iran, Syria, Libya, and Egypt.[4][5][6] Syria, which has a history of confrontations with Israel, has long maintained a relationship with North Korea based on the cooperation between their respective nuclear programs. On 6 September 2007, the Israeli Air Force conducted airstrike "Operation Orchard" on a target in the Deir ez-Zor region of Syria. According to media reports, 10 North Koreans who "had been helping with the construction of a nuclear reactor in Syria" were killed during the airstrike.[7]
When North Korea opened up for Western tourists in 1986 it excluded citizens of Israel along with those of Japan, the United States, and France.[8] Jewish people from other countries have experienced problems entering North Korea. Israel has called for world action against North Korea's nuclear weapons programme.[9] It has been suggested that North Korea has sought to model its nuclear weapons programme on Israel's, as "a small-state deterrent for a country surrounded by powerful enemies; to display enough activity to make possession of a nuclear device plausible to the outside world, but with no announcement of possession: in short, to appear to arm itself with an ultimate trump card and keep everyone guessing whether and when the weapons might become available."[10]
In May 2010 the Israeli foreign minister, Avigdor Lieberman, labeled North Korea as part of an "axis of evil"; he stated:
"This axis of evil that includes North Korea, Syria and Iran, it's the biggest threat to the entire world".[11]
In 2014 as the Israel–Gaza conflict escalated, North Korea allegedly negotiated arms deals with Hamas.[12] This was however denied by the KCNA a few days later.[13]
