Trump wants to let Russia back into the G7, but Putin must do these 9 things first

At the time of occupation, Crimea alone accounted for 4% of Ukraine's gross domestic product.

In 2017, Ukraine's Ministry of Justice assessed the economic damage of Crimea's annexation alone to be $100 billion.

Today, Russia holds more than 70 political prisoners from Ukraine.

During the Kerch Strait incident in November 2018, Russia illegally captured 24 Ukrainian sailors. Russia continues to hold them in custody with no official release date.

The Crimean Tatars are a Sunni-Muslim and ethnically Turkic minority group who have encountered much religious and political persecution from the Russians.

In June 2018, five Crimean Tatar activists were jailed for their involvement in anti-Russia protests in February 2014—before Russia annexed Crimea.

Then, in March 2019, 23 Crimean Tatar activists were jailed for associating with the pan-Islamist political party Hizb ut-Tahrir (Party of Liberation), which is legal in Ukraine but banned in Russia.

MH17 was en route from Amsterdam to Kuala Lumpur. When the plane was flying over eastern Ukraine, Russian soldiers fired a missile from the 53rd anti-aircraft missile brigade and shot it down, motivation unknown.

A total of 298 people from 17 countries died as a result. In May 2018, a Joint Investigation Team consisting of experts from Australia, Belgium, Malaysia, and Ukraine found Russia to be responsible for the tragedy.

... regarding the two occupied regions of Abkhazia and Tskhinvali—which amount to 20% of Georgia's internationally recognized territory.

More than a decade after signing the agreement, Russia still has not lived up to its side of the bargain: (1) Russian military forces have not pulled back to pre-invasion locations, and (2) Russia has not allowed humanitarian-aid groups free access to the occupied regions. Several thousand Russian troops are stationed in these occupied regions.

When it appeared that Assad was in danger of being ousted in 2016, Russia militarily intervened and has since propped up the Syrian dictator.

This has since prolonged the killing, which has left more than 600,000 people dead and has turned Syria into a breeding ground for Islamic extremism. The sooner this civil war ends, the better for everyone.

All 17 US intelligence agencies concluded that Russia meddled in the 2016 US presidential campaign. Similar accusations have been made against Russia concerning elections in France, Germany, and Italy. This behavior is not acceptable for a G8 member.

The G7 is an organization that allows like-minded democracies to work together to tackle many of the world's major problems. Putin has not demonstrated that he can be a trusted partner, and President Trump is wrong to say that Russia should be allowed back in the club at this time.

If Russia does change its ways, it should be invited back. Russia is a proud country. For better or for worse, it has a history of being at the center of global affairs. But it can only reenter the G7 once it demonstrates that it is a responsible and collegiate actor on the international stage. This is unlikely to occur while Putin is in power.
