President Trump vs Venezuela (and its allies)

President Trump shocks the world again this time by declaring there is this military option on the table against Venezuela, which sent ahead with the undemocratic constituent assembly election. As the opposition parties boycotted the vote, now the ruling party occupy 100% of the seats. President Trump excluded talks with Venezuelan President Maduro until the nation 'democratizes'.

Venezuela is a oil rich nation that nationalized its oil resources. Having faced with the seemingly utter failure of its economy, the lack of foods and materials and astounding inflation, the nation sought help from elsewhere, notably from Russia. The tie between the nation reportedly started its purchase of weapons. If sactions be successful, that must include all that are involved.

Meanwhile, the desparate move by the State Department and the President, spending considerable political capitals and sacrificing the credibility, need a clear objective other than the US is displeased with the regime.
