According to Bloomberg, Middle Eastern countries are lining up to buy South Korean air defense missiles because the US Patriot missile is too expensive, costing as much as $4 million. South Korea's Cheongung missile boasts accuracy comparable to the Patriot, but costs only a quarter of the price! The Cheongung missile is manufactured by the South Korean company LIG Nex1, with Hanwha Airlines providing the radar system and launch equipment. Both companies are publicly listed. In the ETF market, the $PLUS Korea Defense Industry Index ETF(KDEF)$ holds 18% of its portfolio in Hanwha Airlines and 6.3% in LIG Nex1. After the outbreak of the Russia-Ukraine war, European countries rushed to buy South Korean weapons, and South Korea profited greatly from the Iraq War! Currently, Hanwha Airlines is up over 7.7%, and LIG Nex1 is up over 3%. In the post-war era, I feel that the potential of the $PLUS Korea Defense Industry Index ETF(KDEF)$ is greater than that of the $韩国ETF-iShares MSCI(EWY)$
