The US and Taiwan would likely be able to repel a Chinese invasion, but it would come with heavy losses for both sides, according to an analysis.

War games have been conducted by the Center for Strategic and International Studies to imagine a conflict.

Mark Cancian is a senior adviser at the Center for Strategic and International Studies.

The United States and Taiwan are generally successful in keeping the island out of Chinese control, but the price of that is very high, with losses of hundreds of aircraft, aircraft carriers, and terrible devastation to the Taiwanese economy.

Half of the US Air Force and Navy's combat planes would be lost in four weeks under one of the more pessimistic scenarios.

China would likely suffer more in a conflict with the US than the US would.

The Chinese fleet is exposed in most scenarios.

They would likely lose a lot of ships during an invasion.

War games are designed to show how conflicts will play out. Each side only has military capabilities that it has already demonstrated in real life in this imagined conflict.

The final report of the game will be released in December.

There are two boards with a map of the Western Pacific on them.

The team uses models and tables to decide what to do. The element of randomness is added with the addition of dice.

The ground game of when the Chinese land and the Taiwanese try to defend the island is played on a separate map.

The Wall Street Journal reported that one of the games involved the US being distracted by another crisis in the world, such asUkraine, and the Taiwanese being slow to react.

They plan to run games with even more pessimistic assumptions in the future, including strikes on the Chinese mainland and the role of Japan.

Cancian said that the CSIS would suggest some improvements to US strategy which could deter China, such as buying more long-range missiles and building shelters in Guam and Japan to protect aircraft.

Some military analysts believe that China will eventually invade Taiwan because of the differences between the US and China.

China has pressured governments not to recognize Taiwan as a nation and has promised to "unify" the self-governed island with the mainland by mid-century.

Tensions between the US and China have recently risen, but the US has tried to maintain a balance.

Nancy Pelosi traveled to Taiwan despite warnings from China.

China said it would sanction the Democrat and her family and that it was an egregious provocation.

Pelosi told NBC that the Chinese government can't isolated Taiwan.

Following Pelosi's visit to Taiwan, China conducted military drills around the island.

Less than two weeks after Pelosi's visit, a five-member congressional delegation arrived in Taiwan.
