Pete,
. i just object when any country takes weapons, or sells arms, to another country

Do you not believe that nations without an arms industry should have the right to buy the means to defend themselves?
You mention Estonia. They are in fear of the Russian army on their border. They buy defence equipment, and welcome British and other armies to stand with them against the threat.

BBC, "But today, sitting less than 150km (93 miles) from the Russian border, it is the base for a Nato battle group - here, according to the alliance, to reassure the Estonians and to demonstrate Nato's solidarity to Moscow.
The decision to deploy Nato troops eastwards - the closest its bases have ever come to Russian territory - came in the wake of Russia's seizure of Crimea and its military operations in eastern Ukraine. Many of the alliance's northern and central European members were alarmed, especially the Baltic republics, whose territory, like that of Ukraine, was once part of the Soviet Union."

"The UK commands the Nato battle group in Estonia. It is based on a single British infantry battalion - currently 5 Rifles - with Warrior armoured vehicles, and it incorporates a company of French infantry. They are supported by a small number of British Challenger and French Leclerc tanks. There is also a small complement of artillery, engineers and other supporting arms."
