Vladimir Putin has been plotting a “Hitler-style” landgrab to rebuild the Russian Empire.
Putin, 71, was accused of setting his sights on three main targets after being tipped to seized the Baltics.
Latvian President Edgars Rinkevics warned Moscow could look to conquer Moldova and the Caucasus of Central Asia Regions.
He said: “If Russia feels it has won in Ukraine the temptation will be for it to continue ... if it feels it was defeated, the desire will be for revenge.”

During a three-day visit to the UK, Rinkevics stressed that the security order of Europe will be threatened for “years if not decades to come”.
The Latvian President stressed Riga would likely not face a Russian invasion due to the safety net of Nato but warned about the need to prepare for all types of scenarios.
Baltic nations, including Latvia, Lithuania and Estonia, have a grand plan to build a network of hundreds of bunkers to thwart any potential invasion from Putin.

Ukrainian leader Volodymyr Zelensky warned about Putin’s post-Kyiv plans earlier this year.
Speaking in January, Zelensky said: He wants to occupy us completely.
“And sometimes, the insecurity of partners regarding financial and military aid to Ukraine only increases Russia's courage and strength.

Zelensky identified Lithuania, Latvia, Estonia and Moldova as likely targets.
However, Putin is also not ruling out an attack on British targets for the UK providing weapons to Ukraine.
Foreign Ministry spokeswoman Maria Zakharova stressed Moscow will retaliate with strikes on UK targets if the strikes take place on Russian soil.
Zakharova was echoing concerns first issued earlier this month after Lord David Cameron said Kyiv had a right to use weapons to hit targets inside Russia.
Moscow was outraged by the Foreign Secretary’s comments and responded by holding exercises to simulate the launch of tactical nuclear missiles.
