Trump's move—peace talks need others to initiate, he just responsible for causing a scene?

During an interview aboard his private jet, Trump said he does not support a ceasefire between the US and Iran, and that the ceasefire should be proposed by other countries. He said he had once paused hostilities to help Pakistan, and that Pakistan is great. Regarding the Iran proposal, he said it is unacceptable, and if people do not agree with him, he will directly throw away the subsequent content. He also threatened to destroy Iran’s infrastructure, saying that within two days the bridges and the power grid could be paralyzed; if Iran has any form of nuclear weapons, he will no longer read the subsequent content.
