Britain claims Russia has used them in the Ukraine?
Wither this is true or not, no one can know, since the Ukrainians make many claims about horrible things that are not true!
A thermobaric weapons starts at 44 tones and has the ability to explode in the air sucking the air up, thus causing living things to die of chocking due to lack of oxygen?
It is more likely that the surrender in the Azov steel works was the result of a small nuclear explosion and many of these right-wing Neo-Nazi styled units were not prepared to give their lives for the Jewish leadership in Kiev!
Most nuclear powers will have similar weapons in their arsenals that will be termed in other names, so that they can claim they are more morally clean than the Russians!
Genesis 4:22, 6:5, Ezekiel 38:2-3, Revelation 4:6, 8:10-11, 15:2.
Ask me and I will tell you!
