Asia-Pacific markets mostly fell on Monday following US airstrikes on three Iranian nuclear sites over the weekend. US President Donald Trump called the strikes a "spectacular military success." Although he had earlier said he would decide within two weeks on involvement in the Iran-Israel conflict, his weekend actions aligned with reports from last week. After the strikes, Trump also raised the possibility of regime change in Iran, one of the major oil producers worldwide.
