China's border actions against India have been described as a "salami tactic". China seems to be seeking to dominate territory through incremental operations too small to attract international attention and not large enough to spark an actual war with India -- but sufficient to accumulate real results over time in the form of gained territory. It is similar to the tactic China has been using in the South China Sea.
For this purpose, China uses gray-zone warfare, a maneuver at which the country has become expert, especially against Taiwan. The concept entails actions that fall just short of war -- others have termed it "indirect war" -- but the purpose is the same: to overcome resistance -- or a perceived enemy -- by inducing exhaustion.
"Overall, China's increasing ties to the Indian Ocean and beyond have expanded enormously over the past two decades.... Crucially... it appears that China does intend to develop some sort of Indian Ocean force." — Christopher Colley, Wilson Center, Washington D.C., April 2, 2021
"If India is weakened militarily and economically... its value as a counterweight to China and the broader U.S. goal of countering China's regional influence would also be undermined." — Daniel S. Markey, Council on Foreign Relations, April 19, 2021.
The outgoing head of Israeli foreign intelligence service Mossad has suggested that Stuxnet wasn't the only spanner in the works his agency put into Iran's nuclear programme.In an interview last week, Yossi Cohen intimated that Iran's uranium-enrichment centrifuges at the Natanz facility had been physically destroyed in the past year, requiring a rebuild. Although Cohen did not explicitly take credit for the sabotage, he made it clear Israel was bent on stopping Iran from building nuclear weapons.
