No, the prevalence of one party dominance system did not affect adversely the democratic nature of Indian politics because the dominance of the Congress party in India had not happened in compromising democracy. It had happened under democratic conditions. Many parties contested elections in conditions of free and fair elections and yet the Congress managed to win elections. The Indian condition was similar to the dominance of the African National Congress in South Africa after the end of apartheid.

The roots of extraordinary success of Congress Party go back to the legacy of freedom struggle. Congress was seen as the inheritor of national movement. Many of our leaders contested elections as Congress candidates and won the elections.
1. The key role of Congress in the freedom struggle gave it a head start over others.
2. The Congress accommodated diversified interests, religion, beliefs and aspirations to strengthen democracy.
3. Despite being taken place of free and fair elections, Congress won elections in the same manner again and again.
4. Congress party consisted of various factions inside itself, based on ideological considerations who never taught together or went out of Congress.
5. Hence, on the basis of above mentioned criterion, it can be concluded that Congress strengthened ideals of democracy and held unity and integrity of the country

Nehru regarded conduct of foreign relations as an essential indicator of independence because it sets a country free to pursue its national interest The reasons for this statement are as given below :
(i) After the World War, there were two blocs led by US and Soviet Union. NATO and the Warsaw Pact came into existence. The countries who had joined these alliances could not go against the US or Soviet Union or other members of the alliances. The clauses of the alliances were binding on them
(ii) India did not join any group or alliance. So India could follow an independent policy. For example, in 1956 when Britain attacked Egypt over the Suez Canal issue, India led the world protest against this neo-colonial invasion.
