In January 2020 the United States lifted restrictions on the deployment of anti-personnel landmines by American forces. This ban had been imposed in 2014 for American troops everywhere except those in South Korea. That decision was criticized worldwide because most nations had signed and ratified the 1997 Ottawa Convention banning the manufacture or use of landmines.

The new American rules allow U.S. troops to use landmines that are activated or deactivated electronically and permanently deactivate after a set period or when their battery runs out of power. The American believe the mines are essential in Korea because North Korea has been threatening to attack again because the 1953 armistice halted but did not officially end the Korean War (1950-53). The North Koreas regularly remind the U.S. and South Korea of that fact.

The U.S. also believes the Ottawa Convention is largely a failure because landmines are still widely used. While 161 nations signed the Ottawa treaty, the 36 which did not comprise some major military powers like China, Egypt, India, Iran, Israel (and the Palestinians), both Koreas, Pakistan, Russia, Saudi Arabia, and the United States. Most of these nations still see a pressing need for landmines, although many are trying to find replacement weapons.

Landmines were outlawed in 1999 but most of the nations that rushed to sign the Ottawa Convention either didn't have landmines or didn't have any reason to use them. While landmine casualties have declined from about 20,000 a year when the Cold War ended (1991) to about 5,000 now, that was largely due to the collapse of many communist governments, which were always the biggest landmine users, mainly to keep people from entering or leaving their territory. The fall of communism led to more open borders and a lot of mines were taken out of service. Thus the treaty backers like to take credit for 87 countries destroying 46 million landmines. The reality was that most of those mines would have been destroyed anyway because the collapse of so many communist governments made most of those mines unnecessary and for retirement and destruction.

Despite the anti-landmine efforts, some countries still manufacture and use them. In the last few years Israel, Libya, Syria, North Korea, Iran, and Myanmar (Burma) planted new mines. Although some nations that still use landmines, like Israel, have taken the lead in developing new technology and techniques for quickly clearing landmines, especially old ones whose location was never recorded.

In addition, there are three countries still manufacturing landmines (India, Myanmar, and Pakistan). Arms dealers still provide large quantities of Russian and Chinese landmines, many of them Cold War surplus. China, Russia, and other communist nations were the major producers of landmines during the Cold War. The mines were produced not so much for use against potential enemies but to aid in keeping the borders closed and preventing citizens from leaving these unpleasant dictatorships.

There has been a growing list of outlaw organizations that are ignoring the 1999 ban. The Taliban in Afghanistan and Pakistan are manufacturing landmines in primitive workshops and using them against Pakistani, Afghan, and foreign soldiers, as well as Afghan civilians who refuse to support Islamic terrorism. Rebels and gangsters have not signed the international agreement and find the mines a cheap way to control civilian populations and slow down the movements of the security forces. It takes more time, money, and effort to remove these mines than to place them.

Despite the 1999 treaty, landmines are still causing over 5,000 casualties a year worldwide. About 20 percent of the victims are killed and 90 percent of them are males. This is largely because men are more likely to be out in the bush or working farmlands that still contain mines. A third of the casualties are security personnel (police and soldiers). This is because in many countries rebels and criminals are still using landmines, either factory made ones from countries that did not sign the Ottawa Convention or locally made models.

Landmines are simple to make and workshops are easily set up to do it. There's no shortage of mines out there, despite the fact that so many have been destroyed in the name of the 1999 Ottawa Convention. There are believed to be over 100 million mines still in the ground and at least as many in military warehouses for future use.

The 1999 Ottawa Convention was supposed to have eliminated the threat of landmines. It hasn't worked because the owners of the largest landmine stockpiles, especially Russia and China, refused to sign. Chinese landmines are still available on the international arms black market. China is believed to have the largest stockpile, mostly of anti-personnel mines. The old ones are often sold before they become worthless. But even these mines, which go for $5-10 each, are too expensive for many of the criminal organizations that buy them. Land mines, competitive with the factory built ones from China, can be built for less than $3 each. You can find all the technical data you need on the Internet.

Meanwhile, the most effective way to get the mine clearing done is by training local volunteers to be part of the part-time mine clearing teams. The government must provide training, pay (which should be good by local standards), and health and life insurance. When a new bunch of mines are found (usually by an animal coming across them), the team gets to work.
